The photo from Tunis confirms this. The driver without doubt is Louis Braillard (not M. Braillard as captioned). Interestingly the registration "695L" belonged to Swiss importer Dr. Josef Karrer who used it on different cars (in Switzerland registrations belong to owners not to cars)

4923-NV1 is a works registration from 1931. Have no specific car adopted to it, but 4922-NV1 was Chiron's #51133, and 4924-NV1 Varzi's #51125. See no relation at all to #51134.

4922-NV1: Registered by Automobiles Ettore Bugatti at Préfecture du Bas-Rhin on 15th July 1931 as #51135

Uwe, what is the source?

Data is confusing, #51135 was sold/delivered to Chiron only as late as September 1932, whereas the registration 4922-NV1 he had already one year earlier at Brno (see photos below, the "1.12.1932" had nothing to do with the date the photo has been taken). Therefore I believe this was #51133, his earlier car. On the other side, the Brno car may have been a works car then which had been sold to Chiron only later.




The registration of #51134 would mean that also this car was a works car before sold to Switzerland.

M.Braillard is Mr Braillard so is correct unless Louis had a brother with the initial M.

wonderful picture.What date is this? It shows the proper way of wiring body screws in a straight line on one panel only [no over laps] so that only one panel at a time needs to be unwired during a race.Very smart engine finish as well.

no problem.I wish I spoke dutch as well as you manage in english.....

I can certify that he speaks excellent Dutch but he is German!

Here a picture taken at a later date when owned by Erwin Troeltsch who apparently bought the car in 1936.If you are interested, I also have a pricture showing the car (on wire wheels) just after the crash where he lost his life.

The Bugatti Trust photo shows the car in 1935 when owned by Rudolf Steinweg (see his name on the cockpit). The Troeltsch photo is from 1937, watch the different head rests.

It is correct that Steinweg bought the Burggaller car (#4842, ex Bremme), but he only used the T51A engine of it which he mounted into his T35C monoplace (ex Leiningen, ex Kappler) he built in 1934. The Burggaller car at that point was already converted back to standard configuration, it had never a slim singleseater body as the Steinweg car, always the original GP body with the stearing moved to the center and a headrest mounted on the tail. Steinweg put the T35C engine into the Burggaller car and sold it (most probably to one Rud. Haller of Munich).

However, there is photographic evidence that in 1935 Steinweg raced also another Bugatti, also a monoplace with a T51A engine. Contrary to the other one this had small brake drums and a short stub tail. The radiator cowling was similar but not identical to the other car. It is my believe that this was the T37A #37350 to which the surplus 8C-1500 engine from #51134 had been mounted.

The Budapest accident car has been offered by advertisement in June 1936 (fully rebuilt and overhauled), and bought by Ernst Troeltsch. In 1937 he changed the layout of the head rest, and the car stayed in this look when owned by Leonard Joa in 1938. Tragatsch wrote that Joa sold it in 1939 to H.G. Martin, but looking at the pictures the car of Martin at the 1946 Ruhestein hillclimb is another one. Strange enough it also looks different than Steinweg's 1935 2nd car, but fully identical with the Mulhouse monoplace. And as that car carries chassis number #37350, then the circle is closed.

This is the car after the crash by Steinweg. By the way, I seem to have read "somewhere'that these monopostos were built or at least sold by Hackelohr of Berlin a well known Bugatti dealer and mechanic also active post war.Any onformation someone??
Sorry, I don't understand Hungarian so if someone can translate?

Hackelöer was a Bugatti dealer at Berlin-Halensee, Katharinenstrasse. He may have been involved in the Burggaller conversion (he was at home in Berlin), but very unlikely in the Steinweg cars (he was from Munich).

I know this accident photo, have also another one taken from the rear. The car had the typical Bugatti tail, somewhat slimmer of course, and with this omega-shaped headrest.

Hereunder the other Steinweg monoplace, taken at the Schauinsland hillclimb 1935.

What a great thread.One of the best I have seen on the site.I love this photo.As a mechanic I would love to restore this car.At the time though it would not have been done.There was no time for busy racers to carry out such a monumental task.Look at the position of the rear axle,diagonal across the car.What damage lurks beneath the bodywork? Lugs broken off trumpets,spring eyes opened out? And how did the front axle with its springs come off,and in what state did this leave the front dumb irons ? I would need two years to repair this car.At the time it would have been a case of taking the engine and fitting it to a cheaper and complete T37 or T35A etc.Fascinating.
