Yes, you've pretty well nailed it there qwaszx.
It's not a Delahaye but 1949 Antem DB-Citroen.
There is some debate about whether it's the same Antem DB that I thought had been puzzled before (but I can't find it so it's pictured below) but modified, or if indeed it's exactly the same car with a photoshopped grille, but I believe from what I can glean from various sources that it is a different, slightly later, car with a number of detail differences.
I'll call it solved and give you the point.
