It is a double front R4, I find 2 names for it: GEMINI RENAULT 4 4L R4 2 avants (Gemini is actualy mentioned on the front wing) and as Renault 4L SINPAR.
SINPAR was a French automobile company which was founded in 1946 by Léon Demeester and that was the factory that produced the Renaulr 4X4 vehicles.
