Two cars were made in 1929 to race at Le Mans. Number 27 was the car driven by Valon and Gregoire in 1929 and 1930. Gregoire placed first in his category and seventh overall in 1929 behind Bentleys and other big-block engines. The Tracta A has a four speed gear box with overdrive specially designed for the Le Mans race track. Its top speed was 140 Km/hour (90 miles per hour). The same car raced all over Europe, at Francorchamps in Belgium and at San Sebastian in Spain.

Other than a new coat of paint, the car remains original. The trunk and spare wheel were mandatory for racing at Le Mans during this time. All caps (gas, oil, water) are mounted with a big washer with many holes. After adding fluid in the pit, the caps were sealed and the seal could not be broken without the Commissaire supervising the operation.
