All these cars are Lancers, made by Eric Irwin in the early 1950's.
This picture is taken from a brochure he produced and show (from left to right) the Series 1, 3 and 2 cars.
He also made a 4th series, not shown here, and there might even be more!
Not a great deal is documented about these cars but certainly at least one still exists!
A series 2 Lancer appeared in the film 'Johnnie Dark'.
Lancers are some of the very earliest production fiberglass cars made.
