Well done!
Specifically, it's a Rochdale Olympic Phase One Lightweight, one of only four such cars built by Rochdale Motor Panels. The car was ordered in lightweight form to compete in Sports and GT races, and was built around components from a Lola Rejo.
The specification of the car is quite interesting in that the front suspension is a combination of standard Rochdale Olympic (Riley 1.5) uprights onto which have been grafted the hubs, discs, calipers etc from a Lola Rejo, the front wheels also are Lola magnesium alloy, the rears being Brabham magnesium alloy.
