Round radiators revisited

When I recently identified the Maudslay, Kevin Atkinson asked if he could see more. I thought about it and decided it would be a good idea, but not only round radiators. During the year a number of posts will appear on pre-WW1 cars and how to identify them. A friend told me not long ago, that every make or model has at least one unique feature, which makes it recognisable. I tend to agree with him. Besides, the lead photo will show a car on which you can practise your skills. The cars will not be very rare and there will be no reward except your own satisfaction to have identified it. The first correct answer (through the comment box) will receive the honors.

But first returning to the round radiators list. It is my opinion that not only the list is far from complete, some important makes are missing and others just don't belong there. Just to name a few more: Beeston Humber, Cottereau, Fawcett-Fowler (an english steamer), Fouillaron, Georges-Roy, Marlborough and the suiss Sigma. Other shapes like round radiators with a straight bottom (like Pilain and Hotchkiss), standing or lying ovals, egg-shaped radiators, radiators with a profiled top (like Speedwell) all deserve their own lists. Some makes shouldn't be on the list at all in my opinion, like Chenard & Walcker, Royal Star or Sava.

How to identify all the different round radiators? My advise is to collect images, look at differences like louvres, bonnet grips, filler tubes and caps, the inner core of the radiator, emblems etc. etc. So start practising immediately and tell me the make and year of the lead photo. The only clue I'll give is that it's missing on the list!

I see no mention of the round radiators of the Calthorpes. My Grand Father, Leslie Porter came 4th in the 4 inch race inthe IOM in 1908.

Do you think so? I'm not sure, but the owner is known. In the register for the city of Voronezh (Russia), the car is listed as Schneider, 16 HP (tax HP).

This is a tin replica toy car. Says for display only not a toy. Just wondering if it represents a particular brand make or is it just a generic art creation?

Hello,
Many brands have actually released automobiles with a round radiator:
- De Cosmo: the last vehicles came out in 1908 with a round radiator.
- Germain: from 1907, the radiator became round and will remain a characteristic of the brand
- Ours (1907-1909): all cars had a round radiator.
- Gallia (1912-1914): made in Charleville in France (do not confuse with other Gallia brands), the round radiator was found on sports cars. (Thank you Fons for this rare photo)
-Spyker: a car of 1906 with a round radiator.

Dear Martin, that is an interesting photo, which I bought myself recently too. The car appears to be a Britannia, one of these rarely seen British makes with round radiator. Judging by the packed car the occasion seems to be a tourist excursion through this remarkable town, which is completely preserved still in present time. The uploaded magnification shows the car in more detail. Also uploaded a part of an identification series appearing in the Automotor Journal of 1906, dedicated to the Britannia.

Hi Ariejan. Thanks for your reply. Very helpful. It seems to me likely that this is the same car with the starter handle blocking the view of the "2".
Thanks once again.

Hi, I have an old postcard of Shanklin in the Isle of Wight, England. The card is dated in the 1920s but the car appears older. It has the reg number DL39 and a round radiator. Can anyone help me identify the make and date?

There s a picture of a car in the ghost town of Bodie Californa that I am trying to possibly figure out the identity of. It appears to have had a round radiator. Any ideas?

With "double" purse($50,000.) of 1911, the 1912 Indianapolis 500, this time round with a 75mph full lap qualification, the race was won by number 8, Joe Dawson aboard a NATIONAL, yet for ALL but the first and last 2 laps, Mercedes had been a continent ahead.

Delaunay-Belleville was already on the original round radiators list by Fons Alkemade (click on the Maudslay link). I only showed here examples of makes which were not on that list.

The honours this time go to Robbie Marenzi. The photo is from the Cycle and Automobile Trade Journal of January 1905. This round radiator was introduced end of 1904, which was described by Motor Age of December 1904 as being an 'imposing cylindrical motor bonnet'. It was continued until 1908, when a new type became available as an option. This new type became very familiar during the successful racing period of National in the years before World War 1. America never counted as many round radiators as Europe and most of these are very obscure makes like Bailey, Haydock or Klink. Several makes indeed had round hoods but were lacking a radiator: these open ends were needed in the cooling of there air-cooled engines (like Franklin and Richmond).
