While
a good part of the 750GT’s alure/enigmatic character is the tendency for
body/trim variations to come and go – often on a far from systematic basis –
‘loose’ record keeping at Corso Marche has left us with real difficulty in
their charting/dating. So the survey of
key external body areas/trim that follows is offered only on an indicative
basis and cannot be considered definitive.
I have frequently referred to the Image Archive within the Fiat Abarth 750GT Zagato Forum. Many of the illustration captions (and thus the abbreviations) below are as recorded in the Image Archive. Please let me know if you identify any possible image copyright issues.
Roof: The following points stem from John de
Boer’s Fiat-Abarth "double bubble" study (January 2018):
- Cars built by Zagato
before the formal agreement for the creation of the 750GT as an Abarth model,
designated Zagato Serie 1, have a ‘smooth’ roof. This includes the very first car, #001766,
which was built by Zagato for Ovidio Capelli, a Milan dealer. John also cites the following as thought to
be smooth roof/Zagato Serie 1 examples: #091978 and #118619.
- The first 'Double Bubble' designated as such in John's database is #145806, with date attribution of April '56
- Reversion to a 'smooth' roof occurred in February '58 with the introduction of the Record Monza Model. However, the cars not powered by the bialbero engine continued to feature the twin-hump roof line, but see note on the Sestrière model below
- The Sestrière model introduced in April '59 for the U.S. market featured a smooth roof line
The
Abarth Buyer’s Guide by Pete Vack refers to a 3rd series of the
750GT, noting: ‘By late 1957, Abarth and Zagato had reached consensus on the
definitive 750GT. The Series III was
built with variations for European and American market cars. The classic 750GT Series III for the United
States had much higher twin domes.’

Engine
Cover: The twin bulge form engine cover, ‘extending’
the lines of the roof bubbles, is evident from earliest production. In addition
to these two air intakes, there is another, horizontal, aperture just over half-way
down the panel and located above the model script badge and vertical cover
handle. Along with the smooth roof, the
Record Monza’s engine cover on the model’s introduction differed from that of
the Double Bubble, a single large duct replacing the twin intakes. Because of the bialbero engine, the Record
Monza’s cover also incorporated a hump to accommodate the power unit’s higher
profile. As seen in the photograph of #757464,
above, the Sestrière’s engine cover, though retaining the Double Bubble’s twin
intake format, rendered these with a more boxy, less curvaceous profile.

As
mentioned above, a feature of ‘Corsa’ specification cars was said to be a ‘Mille
Miglia Motore’ badge affixed to the dashboard. Though this may well be a matter of personal
customisation by the owners, examples have been seen of this badge being
mounted on the engine cover of Double Bubbles and Record Monzas.

Windows,
Glass, Plexiglass: Double Bubble models featured
6 ‘glass’ areas: front windscreen, rear screen, door glass, rear quarter glass,
between B and C posts. Plexiglass
was substituted for cars destined for competition use from the outset. The substantial variation was confined to the
Record Monza model, wherein a small triangular window was let into the area
between the B and C posts, and under the outer edges of the rear screen.

Front: From the earliest chassis numbers, the front
panel featured a grille and a horizontal bar, tapering to a point, either side,
(sometimes referred to as ‘whiskers’), mounted a little above the leading
edge, and slightly lower than the level of the headlamp fairing apertures. Because of the curvature of/bulge in the
front panel, the central grille is convex.
Contemporary replacements are available from Fiatplus.com. and
supplied in either ‘thick or ‘thin’ form.
The grille is two part – outer ‘shield, ’ chrome meshed, with a smaller
central rendition of the traditional Abarth marque, Scorpion badge.

 |
| ‘Whiskers’ currently available from Fiatplus |
However, again from early production, some cars wore only the
central grille, with no whiskers, e.g. #162696.
Another instance, #239600, shows a further variation – no whiskers, but
a pair of vertical bumper bars. #417338 is
illustrated while undergoing bodywork restoration – the 14 factory-drilled
mounting holes are clearly evident, per side: accommodating the lower lamp
surround trim, two, one above the other for the vertical bumper bars, two,
horizontally aligned, to carry the whiskers, central hole for a number plate
(?) and one for the upper quadrant of the central grille.

The latest chassis number I have found which carries the
central grille and whiskers is #720384.
Later cars, e.g. #756808, fitted with the full width/wrap around bumper
bar do not carry the whiskers.  |

Late cars have an additional ‘Fiat’ script badge mounted
above the central shield-grille/Abarth crest.
According to the Abarth Buyer’s Guide by Pete Vack, this script
was introduced in late ’57 on the ‘Series III’ American market cars.

Below
the headlamps, a small, aluminium cased circular/cone-profile indicator
(usually with a clear lens) is mounted. On
the late versions the location is seen to be above the wraparound bumper. Underneath this lamp, a small rectangular,
sometimes chrome framed aperture provides for the intake of air to help cool
the front brakes. The earliest clear
photograph I have found of this modification is of #462534. Absence of this feature has been said to be
an indication of the car being a Corsa version.

Headlamps: Circular, and
mounted at the rear of a faired-in aperture, the 5.5” units were usually
provided with a Plexiglass front cover from early production. This remained the common configuration until
late in the production run – last photographed - #720384. Then, along with the full width/wrap around
bumper, the lamps were located further forward on the leading face of the front
wing, upright and chrome-rimmed, (#734541).
Cars built for immediate export to the U.S. featured 7” covered headlamps.

Side Badges: A constant feature
from the beginning of production was the placement of a black Zagato Milano
‘Z’ badge on the front wings between the rear of the front wheelarch and
the leading edge of the door.
The rear quarter panel
badges – upper depicting a triangular checkered flag with ‘Gran Turismo 750’
script/block arrow with script referring to Italian national championships;
lower is the Abarth crest - are not seen on cars as late as #441784 (July-‘58); they are evident on #446004 (August-‘58). The Record Monza lacked badging on the rear
quarter panel, but had model and Abarth crest badges applied to the B post area
between the door and rear side windows, as seen on #441205 mid-‘58).

The
Double Bubble rear 1/4 badges vary according to year of manufacture. For ’58-made cars, the upper badge commemorates
the Italian Championships of ’56 and ’57.
For ’59 and ‘60, the badge was amended to add the ’58 Championship
victory.

Rear:
The profile of the rear
face of the rear wings is ‘blunt’ (radiused) on early cars, e.g. #248883,
below. Note the simple, small taillight
units. The wing profile over its
trailing edge was modified, (creating what was referred to by Greggio as
‘little tails’), and a larger, deeper (proud-standing) taillight unit
introduced subsequently, e.g. #602924, below.
However, the Record Monza incorporated the ‘blunt’ rear profile, e.g.
#577535.

Rear
light cluster:
The earliest (mid-’56) chassis number I have for reference, #163327, features a
three section lens, top to bottom, orange, red, red – still in use on #358847. A narrow horizontal chrome bar separates the
upper (orange) lens from the middle (red) one.
The top and bottom are (vertical) ellipse shaped, broader at the top,
sharper at the bottom. On #248883,
(early-’57), a variation of this type has the lower red lens projected outwards
and with a chrome ‘casing.’ Also evident
on other ‘early’ cars, #244318, (early-mid-’57), for example, is an elongated
oval with a central circular, darker section.
All these variants have a chrome surround. #443582, (mid-’57), features an all red lens
with central, horizontal chrome bar divider and this is commonly seen, as late
as #757464, (Sestrière, ’60), for instance.
First seen on #558321, (’59), is a type which is then common as far as
example chassis #830648, (’60-’61). The
chrome surround of this has a sharp ellipse top and bottom. A square red stop light lens projects from
the centre and this is held by a chrome casing.
On #617839, (‘60-‘61), it is seen that the top ellipse is much blunter
than the lower one. |

Rear
Bumperettes/Bumper Bars. The first basic
distinction would be that a car delivered to a customer whose primary intention
was to race it, would have no bumperettes at all. On the early (mid-’56), chassis number,
#163327, a pair of vertical bumper bars is fitted on the joint between the
lower rear valance and the rear wing. As
with many other examples of rear ‘body furniture,’ it’s impossible to judge
with certainty, but I’d suspect these are a later addition. However, this configuration is also evident
on the early chassis, #244318, (early-mid-‘57).
The earlier cars were sometimes fitted with a number plate surround in
chrome which provided, in effect, two vertical bumperettes of smaller
proportions. This arrangement is seen on
#222623, #239600 and #248883 (all early-’57) and #244318 (early-mid-’57). It seems to have been a short-lived solution,
being superseded in late ’57 by the installation of a pair of horizontal
bumperettes, doubling as registration plate lamp bulb holders either side of the number
plate mounting, to #418163 (’57). This
style/level of rear bumper provision then became a norm until the eventual
cessation of production. A late example
is #749634, (mid-’60). However, also
often seen was a combination of the vertical bumper bars along with the
horizonal pair. An early example of this
is #358847 (late-’57).

Rear
bumpers. Chrome-finish quarter bumpers, effectively
protecting all four ‘corners’ of the car, appeared on Sestrière models
manufactured in ’61 – example, #734541.
Note: Elsewhere it was documented: 02-’58 ES 01, Tipo221 750 Coupe Record Monza Zagato 57 bhp; Greggio says
smooth roof, 3 pane rear window, horizontal wraparound bumpers.

Chrome
rear model script. This is usually found mounted at a 30° angle
across the centre of the engine cover, between the cover’s lock and the upper
horizontal aperture. The script itself
commonly comprises the words, Fiat ABARTH 750. An example is seen on #418043,
(mid-’58). Variations: Fiat/deriva
ABARTH 750 (#651969); fiat derivazione /ABARTH 750 (#558327,
and #446004, (mid-’58)). The deriva/derivazione
is a reference to the programme by which Abarth developed the 750GT as a derivation
of the Fiat 600 model. The 30°
angle-mounted script continued until late ’59, e.g. #693930 (Sestrière). However, a further variation, from late ’59
onwards - is the fiat ABARTH 750 script mounted centrally and
horizontally – not at the 30° angle previously noted, e.g. #706590, also
#694916 and #696265, (both late-’59) and #719212, (mid-’60).

I
suspect that this will forever be an ongoing work-in-progress. By virtue of the type of vehicle this is, and
the sort of enthusiasts that typically own examples, cars seen/photographed
today may well display features which have been added/modified over the years,
long after they left the factory – such customisation is especially commonly
seen in regard to badging, trims and wheels.
And, as regards the details of any 750GT as it left Corso Marche, such
is the accuracy/completeness/availability of the contemporaneously-recorded
data concerning production of the cars, that there will be many aspects of
their specifications which will remain uncertain/disputed. I do not pretend to have access to any magic
bullet processes or data sources which would resolve such issues. All I have done here is to collect together
and systematically organise existing information with what I hope is an
appropriate level of discretion. But,
even so, I’m sure there will be readers with far greater first hand knowledge
of the cars than I have who will perceive misunderstandings/anomalies in what I’ve
written. That being the case, I’m very
keen to receive appropriate feedback so that the document can be refined and
improved – so please don’t hold back!
