Introduction
The original 1956 Studebaker Golden Hawk Authenticity Guide from 1996 was compiled with the
cooperation of members of the 1956 Studebaker Golden Hawk Owners Register. Participating
members responded to questionnaires indicating the color, condition, texture, location, etc., of
items related to authenticity. The results were compiled and compared against other sources to
determine what is probably the most correct condition. Since that time, many new items have
come to light and are included in this new Guide.
Authenticity is a rather nebulous term as applied to Studebakers. During my research, I found
accessories which were not listed in any of the Studebaker literature for 1956 Golden Hawks.
Everyeffort has been made to research the items listed as thoroughly aspossible. I placed more
significance on the Studebaker Chassis, Body, Shop Manuals, as well as magazine articles and
drive reports from the period when the cars were new, than on company brochures and
advertisements which often were printed before the cars actually went into production.
Even relying on magazines from the period was no safe bet. The April 1956 issue of Hot Rod
magazine shows a beautiful picture of the dashboard and steering wheel on page 54. However,
the horn button was from a 1955 model. As for company brochures, the one entitled
STUDEBAKER HAWKS, craftsmanship with a flair also shows a 1956 Golden Hawk dashboard
and steering wheel, however the steering wheel is black, instead of white.
Mine's Original. I have learned to be suspicious of any car described in this way. Decades have
passed, several changes of ownership have most likely occurred, and any number of body shop
visits can do wonders for a car's originality. Even carsthat sat for many years probably had some
modification made during their early years. In many cases, the owner wasn’t even aware that a
change was done. One owner’s car had been inthe family sincenew, but the owner wasn’taware
that the car had a later model Hawk hood. The car had been in two accidents and the hood had
been replaced one time.
Another valuable source of information, although not totally accurate, was the original production
orders. I was able to obtain all 4073 production orders for 1956 Golden Hawks. Even those were
not completely accurate. Several cars were listed with Flight-O-Matic transmission, one showed
a radio from a full size sedan, while many others listed a prototype wheelcover which never saw
production.
There are a few items included here which some might perceive as nitpicking. They are only
presented to raise awareness and to show that there will always be questions, as well as
differences of opinion, when it comes to authenticity. Therefore, this Guide should be used to
provide support for those items which may be questioned. It is not intended as proof that
something on a particular car is or isn’t correct.
Hopefully, this Guide is as accurate and complete as possible, However, this effort is not the final
word. That is why I called it a guide rather than a handbook or manual. In many instances, there
won't be a definitive answer, but rather what appears to be the norm. Some deviations will also
be identified and you can be the judge.
Authenticityquestionscansometimesgetalittletoocomplex.Asanexample,theAC-2799Spoke
Type wheelcovers are a legitimate option for 1956 Golden Hawks. However, they were not
introduced until February of 1956. Would a 1956 Golden Hawk be considered authentic, if it
sported the Spoke Type wheelcovers, and was built before February, 1956?
Although there wereno plansto publishrevisionsor updates tothe original Guide,theinformation
we have uncovered over the past few decades caused me to revisit that philosophy, and offer a
new Guide. Virtually everything pertaining to the 1956 Golden Hawk is stored in the Studebaker
National Museum Archive inSouth Bend. Unfortunatelylogisticsandfinances prevented mefrom
accessing this data. However one South Bend area owner did some extensive research at the
Last Update - July 2, 2018 Page 3

Introduction
SNM Archive and kindly provided me with copies of that research.
I Hope this Guide will be a source of reference for decades to come and for this reason, I did not
include the names of individuals who provided photos, documentation, or other guidance. I can
only offer my heart felt thanks for their generosity.
This Guide does not get into details as to the color(s) of specific wiring,. The parts and shop
manuals have electrical schematics which often provide this information. If an engineering
drawings indicated such information as, “finish gloss enamel”, I included this type of information.
In this Guide, you will find material concerning the questions which our registered owners have
asked most often. References are made to other Studebaker models including the other 1956
Hawk models. Please see the table below for more information on all the Hawk models.
Hopefully, the information in this Guide will be useful to anyone searching for, maintaining, or
restoring a 1956 Studebaker Golden Hawk.

NOTES:
There were 4073 Serial Numbers assigned to the 1956 Golden Hawk Model year, but only 4071
were produced. Two cars from the South Bend factory were scrapped during production, with no
explanation appearing on the production orders. Not counting the two scrapped cars, the final
totalsshow3470carsproducedinSouthBend,Indiana,and601assembledinVernon,California.
Original 1956 Golden Hawks were simply not available more than half a century after the last car
was produced. Restored cars, even those done by professionals, did not always follow the exact
factory procedure to the letter. They were restored based on the owner’s and/or the restorer’s
interpretation.

other items shus as incorrect exhaust extensions or non original back-up lights. Those items are
discussed in detail, and that is where the correct information is located.
Moulding vs Molding - Studebaker used the spelling of the word Moulding instead of Molding in
the parts catalog to indicate many trim pieces. I used the two spellings interchangeably in this
Guide. Although both spellings are correct, Molding is more commonly used here in the US.
Apparently the origins of the world come from Europe where the proper spelling is moulding.

General Information
All 1956 Studebaker Golden Hawks were produced in either South Bend Indiana or Vernon
California. The City of Vernon is an industrial cityof 5.2 square miles located several miles to the
southeast of Downtown Los Angeles in Southern California. Most Studebaker documents refer
to the Vernon plant as the Los Angeles plant. In keeping with that , the Vernon plant will be
usually be referred to as the Los Angeles plant or simply LA. The Indiana plant will be referenced
as South Bend or SB.
No 1956 Golden Hawks were produced in Canada at the factory in Hamilton, Ontario. Although
there were certainly controls at both the SB and LA plants, some items on cars assembled at the
Los Angeles plant seem to vary at times with their South Bend counterparts.
Often there is no indication as to which serial number was affected when a midyear change was
made to the production run. An effort was made to check the production orders to determine the
approximate serial number, with a final assembly date, on or after the date of the change. That
does not, however, guarantee that the change actually was made at Los Angeles.
A good deal of the information shown throughout this Guide was obtained from the original
production orders, the 1955 - 1958 Studebaker Chassis Parts Catalog, the 1953 - 1958
Studebaker Body Parts Catalog,the1956 Studebaker Passenger Car Shop Manual,andthe1956
Studebaker Accessories Manual.Additionalmaterialwasgarneredfrom theStudebaker National
Museum Archive.
While researching this material, I came across a few errors in the parts catalogs, as well as
severalamongtheproduction orders. In mostcases, Iwasabletoidentifythe correctinformation.

General Information
Identification Numbers
Serial Number
The Serial Number plate is located on the left front
door hinge pillar. The Serial Number itself consists
of 7 numeric digits.
TheserialnumbersofcarsproducedatSouthBend
are 6030001 through 6033472. The serialnumbers
of cars assembled at Los Angeles are 6800001
through 6800601.
Although this indicates a total of 4073 serial
numbers, only4071 carswereproduced. Twocars,
serial numbers 6030726 and 6031367, were
scrapped and were not included in the production
total.
There was no reason indicated on the production order for either car, as to why the car was
scrapped. See the production orders on the following page.
For some reason, Studebaker-Packard used
what would be best described as a Roman
Numeral “I” in place of the number "1". Any
Serial Number containing a 1 will have that
Roman Numeral character in its place.
This has caused some confusion whenever a
car changes hands, especially when trying to
obtain, or transfer, a title for a car that was
purchased in another State. The title or
registration will show a numeral “1" while the
character on the Serial Number plate will look
like the letter “I”.
The first two cars were designated as show cars and had final assembly dates of May 23, 1955
and September 23, 1955. The remainder of the South Bend production ran from November 22,
1955 through August 15, 1956.
In between, came the 601 Los Angeles assembled
1956 Golden Hawks.
The first, LA serial number 6800001, was (probably)
built on or before October 27, 1955. There was no
date on the production order, however serial numbers
6800002 through 6800013 were built on October 27,
1955.
ThelastLos Angelescar,6800601 wasassembled on
June 3, 1956 and shipped on July 11, 1956.

General Information
Body Number
Bodynumberswerenot assignedsequentiallytotheSerialNumber,andranged,accordingtothe
original production orders, from 1 to 4063. The number appears under the hood on a plate on the
passenger side of the firewall.
The model symbol 56J, and the body
symbol K7 appear on the top line. The
numeric Body Number is on the next line
and consists of from 1 to 4 characters.
The breakdown for this system is as follows:
• 56 = Model year
• “J” = Engine, in this case, the Packard 352 cubic inch V8 engine
• “K” = Hard Top body style (5 Passenger)
• “7" = A further breakdown of the Hard Top style, used for the 1955 President Speedster,
the 1956 Flight Hawk Hardtop (export only), the 1956 Sky Hawk, and the 1956 -1958
Golden Hawk.

General Information
Body Number - Streamer Ribbon
On some cars with possibly special handling or on some of those equipped with a power front
seat, a streamer ribbon was attached to the right of the body number plate.
This one shows “P SEAT”. I don’t believe every car with the power seat option had the streamer
ribbon.
The streamer ribbon in this photo has the name of Studebaker Engineer, W. G. KNECHT
stampedonit.Mr.KnechtworkedatStudebaker for42years.ThisribbonwithBodyNumber2591
was on one of my cars, Serial Number 6032195.
Here is another example
with the same name. This
body number 2576 was
on Serial Number
6032221.
The body plate was painted the same color as the cowl. I am unsure of the original color of the
streamer. In all the cases I’ve seen, the streamer ribbon is attached at one end only.
(NOTE: Some production orders did not show a body number and/or an engine number.)

On March 6, 1956, AMERICANMOTORS CORPORATION produced its own 190 horsepower, 250 CID V-8 engine. This engine was used
for the remainder of the model year. It used a Carter WGD 2 BBL carburetor model 2352S.

General Information
The Jet Streak Engine
Atonepoint,StudebakerPackard
considered an option called the
Jet Streak Engine. This was
essentially the same engine that
powered the 1955 Packard
Caribbean, a 275 horsepower V8
with dual Rochester four barrel
carburetors.
The Jet Streak option was
contemplated by Studebaker-
Packard, but was never offered
from the factory for the 1956
Golden Hawk. There was even a
part number, 1541805 assigned
to the option.
Besides the dual four barrel
setup, the kit included an
Iskenderian solid lifter cam, dual
point Mallory ignition with the Mallory Mag Spark transformer, and chrome valve covers.
In the photo above, the transformer is mounted on the cowl to the left of the windshield wiper
motor. The transformer replaced the coil.

General Information
Many dealers installed a dual 4 barrel setup, at the customer's request, or the customer had it
done elsewhere since all the parts were available directly from the Packard parts bin. Of course,
not all of these conversions received the cam and distributor.
Here is the option as described in the July 1956 issue of Motor Trend:
"Studebaker's Golden Hawk is a pretty hot potato as it sits in the dealer's showroom
but has so far escaped the active interest of race drivers. A recently announced kit
for factory or dealer installation converting it into a "Jet Streak" may change all this."
"Boosting horsepower to 330, it consists of an Iskenderian cam, 1955 Packard
Caribbean dual 4 barrel carburetors and manifold, chrome valve covers, dual
breaker distributor, and a special coil. Displacement and compression ratio remain
unchanged neither requiring a lift."
I have examined all 4073 production orders and there is no indication that any 1956 Golden
Hawks came from the factory with either a 374 cubic inch engine or the Jet Streak option.”
Many of the original production orders for exports, including Canada, show an item identified as
LC HEAD and/or 8.25 to 1 RATIO. The parts catalog supports the standard 9.5 to 1 ratio as well
as this lower compression engine.
Three of the production orders had a note indicating HC HEAD but I believe this simplymeant the
normal engineas opposed tothe LC Head lowerratio engine.As statedearlier,production orders
contained many variations and even some obvious errors.

General Information
The Jet Streak concept apparently started with a letter from Harold Churchill, dated December
20, 1955.

ThisletterfromCarlB.Thompson,probablyprovidesthebestinformationregardingthe374cubic
inch V8 and the Jet Streak engine option regarding the 1956 Golden Hawk.
Mr. Thompson has been referred to as the, “unofficial historian of the Studebaker Corporation”,
and passed away on December 12, 2007 at the age of 98. Thompson served as one of the
company’s in-house photographers and took literally thousands of photographs. He was also
involved with parts catalogs.
After Studebaker closed its South Bend operation in December 1963, he stayed on with the
company while it went through its close-down period till 1972.
