1954 Panhard X86 Dolomite, with coachwork by Pichon-Parat. The French Racing Blue paint was, of course, a huge hint. Then it was a matter of researching French marques of that era that may (or may not) have raced at Lemans. I must admit that while Panhard was certainly on my list, it wasn't my first - or second - or fifth choice. This is pretty obscure car, at least to me. Hadn't seen it before, and it was not so easy to find. As always, worth the search, though. I found a lot of very neat cars along the way that may well figure in future quizzes!
