A busy road Mystery (update: Edwardian FIAT Tipo 3Ter ? ) ?)

This is probably a Fiat (not F.I.A.T. by that date) and, judging by the size of body, is likely to have been a 3 Ter produced from 1912 to 1915---40 hp from 4,396 cc. Smaller models with similar rounded radiator shells were made---1A, 2B and 3A, the latter two in production until after WW1.

The big pre-WWI FIATS all had angular radiators. I think the rounded radiator so typical of the 501 may have appeared on some of the later Tipo Zeros, but the Zero was a much smaller car that the one in this delightful photograph. Many years ago in my vintage FIAT owning-days here in Melbourne I knew of a couple of big 35/45 pre-WWI FIATS and they certainly had angular radiators. Indeed the era of those lovely curvacious art-nouveau radiators on Fiats was short lived as car makers scrambled to ape the frontal aspect of the Rolls Royce. When the 503 replaced the 501 the radiator was angular.

Not quite right on the rad but the body of this 1920 humber is close.

I agree with John it doe look like a Zust radiator but Mark is more probably right that it is FIAT. Could I suggest that it is in fact a hearse, Bathurst Funerals ran a FIAT in prewar times but it was a flat radiator model with disc wheels. I didn't think that the steam bus ran to Warrandyte, a distance of about thirty kilometres and in those days just dirt roads. I do have information on these steam buses but cannot put my hands on it just at the moment. They (I think four) ran between the Prahran railway station and the Malvern town hall, a distance of around four kilometres.
They were not a succeess and broke down frequently, all were scrapped before the WW1. I will endevour to find the information. David

Fiat seems a good option, though like often: a better scan would help a lot to id (if available of course). In Wonga Park we see a Vinot & Deguingand (on the left) and a BSA. The steam bus is a Chelmsford.

I'd go with the FIAT. One of these which belonged to the De Montmorency family in Kilkenny, after a spell as a hire car with Renehan's garage was converted into an armoured car for use in Kilkenny military barracks during the war of independence in the early 1920s.

It is a WW1-era FIAT, probably a Tipo 3A.

The radiator reminds me of an Edwardian Zust? On studying the image more closely I can see wire wheels with perhaps Laundelette coachwork. I do not think it is of USA manufacture.
