I believe this is Delahaye 135S, chassis no: 801581 built for M. Baylet, owner of the journal "La Depeche de Toulouse". Coachbuilder was Vanvooren of Courbevoie in 1950.
Two 135s were constructed for him by Vanvooren, the other one being 801621 with a different front.
M. Baylet was unfortunately killed in an accident with this car which was destroyed.
