This one is a very prominent car:
It is Simca Gordini TMM 1GCS Sport ('Gordini' book, Roy Smith), built June 1947, first race: 6/07/1947 Reims, #32, Trintignant 3rd place overall
I would feel happy to see the puzzle car's race number and registration plate to be able to clearly identify the race, where it started.
The second picture shows TMM 1 GCS Sport with race number #37 in 1948 (not identical race to the puzzle car):
The car ran two times in 1948 with #37:
1) Bol d'Or 16-17/05/1948: 1090ccm, Scaron, 1st place overall
2) 12h Paris 12/09/1948: 1430(?)ccm, Veyron/Manzon, DNF
Additionally the car ran one time in 1949 with #37 (small different details, like hood fasteners, etc., identical to the puzzle car):
ACF GP du Comminges, 7/08/1949: 1490ccm, Scaron, 3rd overall
