There is no Fiat 503 known to my studies bearing this sort of number. This does not make such a number impossible for a Fiat 503 but I would certainly like to know some details as to why this chassis is believed to be Fiat 503.

The 503 chassis identified thus far in my studies are numbered:

I have questions about certain numbers reported for Fiat 501 cars that may reveal some inconsistencies (perhaps bad data?) when answered?

I've been told more than once that, for the Fiat 501, the first two digits "13" in a chassis number signify "export" examples. That the third digit represents the year. I wonder if the second digit actually represents a chassis length variation that was often exported and became identified "export" as a result?

There is a Fiat 501 numbered 1341704 in the "Museo Nazionale dell'Automobile" in Torino. The museum was born as Museo dell'Automobile "Carlo Biscaretti di Ruffia" when formed and carried that name until relatively recently. The car was displayed as a "1921" example when I looked at it a bit carefully (approximately 30 years ago) but I suspect the chassis & engine date from 1924. Now I wonder what the wheelbase length is! They have another Fiat 501 that I should look at more carefully to identify the chassis number and check additional details.

There is (or was) a Fiat 501 in Australia with a chassis number reported as "1342093".

119xxxx numbers were theoretically issued 1919.
130xxxx numbers were theoretically issued 1920. It seems likely that there were 120xxxx numbers as well?
121xxxx numbers were theoretically issued 1921.
122xxxx numbers were theoretically issued 1922.
123xxxx numbers were theoretically issued 1923.
124xxxx numbers were theoretically issued 1924.
125xxxx numbers were theoretically issued 1925.

"140135" (if there is no reporting error?) may fit among the 1920 cars?
1413841 may fit among the 1921 cars?
Hi John,
Thankyou for the research. I managed to get a photo and the second and third photo basic enhanced, I will try again later.
So far can only see **41537
Regards Steve

Here is a zoom.
Is it 3141537 or 1341537?

Interesting project. It really is a 503 chassis, although the rear part looks to be boxed rather nicely.

I am collecting parts to complete my Fiat 501, which, according to Fiat Centro Storico, was made in autumn of 1925 as a bare chassis. It already had a higher compression head and huge front brakes as it was one of the last 501 produced before the model designation changed to 503 with minor modifications. As my rails were covered in rust, I gently wire brushed them and wiped the dust with some solvent before copying the fainted number to a piece of paper with a stencil, a trick that I used often as a young boy with some coins. If you can find the first number, let me know, as I can tell quite a lot about what kind of a car it was using my archive notes.

It is not easy to tell if the front axle is from a similar Fiat, I suspect that it is not and also the springs look wrong to me. The rear axle is certainly from something else, could it be from a 102 series Alfa-Romeo or some Austin or Holden then? 1920s Fiats had very beautifully casted torque-tube rear axles with an oval differential casing, which I sadly haven't been able to find in complete form here in Finland. As it happens, I've been able to find a lot of smaller parts for my car from Australia, which was an important market for Fiat in the 1920s and 501's seem to have survived well there.

Fiat 501S, Siata 1500CTS, 1600SS, 1300TI, 1750 Berlina, F12, 3x2000 Berlina, 2x1600 Super, 2x1600GTJunior, Alfetta 1.8, 127, 128, 156 2.0JTS
