B of B models

I was only on the set at Duxford for one day ,I seem to remember some full size replica spitfires with a car starter motor driving a mock prop with just a smple seat in the cockpit.I seem to remember pushing them around into position at some stage during the day!The only flying that day was a twin seat Bouchon 109 that took up some film VIP person who was sick all over the cockpit!
