by Lagache and Glaszmann ?

Lagache & Glaszmann is what I expected as an answer. But this puzzle put me in doubt when I received the proposal and the photo from "Voisin" and offering me Roger Maleyre; The photo is so similar to my puzzle. I looked for additional information on the web but apart from the attached document, I found nothing more. I'll let you debate this car, you certainly know more about it than me. The point goes to Saco

[SACO]

Please , just a little extra point !
