Thanks for the point Gerd! I deliberately did not try to identify the driver because of so much conflicting information. For example the picture I posted clearly identifies the driver as Charron, yet in my reference this very picture has an added caption which states that the driver is Girardot. My opinion is the driver shown in the picture is Charron, as the information seems to be part of the original photograph, whereas the caption was added later, however this could be faulty logic. In another reference I found that Charron and Girardot were competitors who drove identical P-L 8 CV cars for the same team. Still it is extremely unlikely that both names were correct for the same photograph unless the drivers were identical twins who dressed alike.
