Apparently re-re-opening this thread.
Looking for profiles of early Le Mans 24h car manufactures, I'm currently searching for info regarding Bignan, a French manufacturer. Since this thread is about as comprehensive on detail as anything I've found so far, including a search here at TNF, I think questions would do nicely in this thread too.
The only other usefull info I have gained is that bore and stroke was 75 x 110 mm qualling a 1979.2 cc displacement although the sole 1926 car had a capasity of 1984 cc. The marque appeared at Le Mans at four consequetive occasions from 1923-1926. I have a vague reference to Renault delivering chassis to Bignan at one point and that a Causan was responsibal for the 2-litre engine. A search at Wikipidea turned up a French commune, but nothing else.
Here's a link to a picture of a model from ebay:

http://www.forum-aut...t377390-875.htmSo where and when started Bignan and when did they end? Were their Le Mans starts facotory teams or privateers – there's a certain continuity among drivers from year to year?
Here's their Le Mans record from various sources:
1923
#23 Bignan 11hp Desmo / Raymond de Tornaco, Paul Gros / 3rd and winner in 2-litre class
#24 Bignan 11hp Commercial / Philippe de Marne, Jean Martin / joint 4th and second in 2-litre class
1924
#10 Bignan / Jean Martin, Philippe de Marne / DNF in 3-litre class
#11 Bignan / Jerome Ledure, Jean Matthys / DNF in 3-litre class
#28 Bignan / Raymond de Tornaco, Barthelemy Bruyere / 10th and 5th in 2-litre class
#29 Bignan / René Marie, Henri Springuel / DNF in 2-litre class
1925
#32 Bignan / Jean Martin, Jean Matthys / DNF in 2-litre class
#33 Bignan / Henri Springuel, Pierre Clause / 12th and 5th in 2-litre class
1926
#25 Bignan / Robert Gautier, Pierre Clause / DNF
Having a look in the Brooklands Books Le Mans 1923-1939, has given a few other pointers. Front wheel brakes (!) were apparently part of their general competitiveness with bigger engined cars. Effective pit work was another – perhaps gained from their previous race record as seen earlier in this thread. Perhaps not surprisingly the 3-litre cars of '24 was running for overall contention but retired, while #29 was running in third as late as the 20 hour mark, looking for another class win only to retire too.
From the 1923-report it says the following regarding their engines:
the one with the positive valve closing mechanism was particularly fast for its size. Compared with its companion, having spring-operated valves, it had a gain of 800 revolutions a minute and about 10 h.p., its maximum engine speed being 4,500. With its comparatively low final gear ratio it touched 4,200 revolutions on the down stretches. I guess the car referred to is the #23 car.
Hope this will be of interest and another stop on the never ending steps of motorsport knowledge!
