Alright, I'll look for a quite known maker that is not in this list:
Amilcar,
Arista,
Barbier,
Bernardet,
Bugatti,
Chenard Walker,
Citroen,
DB,
Facel Vega,
Ford France,
Gregoire,
Licorne,
Panhard,
Peugeot,
Renault,
Rosengart,
Rosier,
Salmson,
Simca,
Talbot
...and built those 2 cars.
Last question before I start looking into some books: was this maker active post 1949 and this is a sort of 'revival' project or the maker was active in the 1952-1954 period?
