Okay, I'll keep trying.
The base car is an Alpine A110 GT4 (also called type A110L). Built from 1963-1969 from parts of the Renault 8, the fiberglass body was made by Chappe & Gessalin.
The vehicle shown seems to be a Group 4 racing variant.
Is this correct up to here?
I am still looking for the team that built the car for racing.
