Generically known as Mark 1’s, the all Triumph based cars had subtle changes in body and chassis design from the prototype.

According to Paul Moorhouse’s notebook of the time, the generic Mark 1 all Triumph kit was divided somewhat confusingly, into three types listed as:
•    MK 1’s – Chassis numbers 1001 to 1033*
•    Mk 2’s – Chassis numbers 1034 to 1057
•    MK 3’s – Chassis numbers 1058 to 1285
*Doors were an option from quite early on and don’t give an indication of age, as some late cars had none.

The last Triumph based car (chassis 1285) was produced in June 1983. Of the 236 all -Triumph-Herald kits produced approximately 160 are known to have been put on the road. Information on some of these cars is very sketchy indeed and doesn’t allow for re-registration of more than a couple of cars.

the roadster throughout its period was deigned on the Alfa Romeo 8C 2300 Monza Spider Corsa.
