I was 19 when i made this . 40 odd years ago ! There was a fellow in the next village called Dave Champion who made convertible minis , HA vans , and the Rapid convertible for Skoda .. He had a black Cooper with a "Concorde " trailer , and I asked him if i could copy it.
I have to presume the engine scoop is simply bolted on the bonnet? certainly a good reminder that the RSPCA has existed since the 1800's. (and yes I bought the magazines (Car craft?) and wore plaid pants so who am I to judge)
