2 George built my fathers Imp engines 75-82 and many other local racer engines but he also had some German and Scandanavian customers too
3 John Homewood original used Ian Carter built engines he didnt use Bevan engines till 77/8 season when he was then running the Davrian floor pan Imp which he had specially built for 76 or 77 season
I know John had 2 steel shell Imps the 2nd car i was told was now in Ireland
4 Ginger Marshall used the Mini traveller chassis for the LWB over the Mini
His first car was steel shell with Mini A series circa 75/6
he later had a Space frame traveller mini built and he then fitted the Imp engine to the mini gearbox circa 78/9
This car later went Hillclimbing
His last car was a space frame Reliant Kitten shaped car and he then had his own alloy engine block cast up and Imp head fitted to it
He still retains the car but has recently been racing Clubmans sport racer
George Bevan died around 97 ish
