I will try to get details of the present state. Jane's book of WWII aircraft says theGriffon rotates clockwise vied from the rear. Any help would be appreciated. So when you are standing in front, facing towards the aircraft it rotates the opposite way. The Merlin anti-clockwise, the Griffon clockwise.
Engine start, runup, flyby, inflight, etc.
I'm trying to recreate very realistic scene of Spitfires on the Silicon Graphics Computer. They sell tapes of most warbird engines. Bill Painter, the curator, carries his tape recorder to all events and gets the sounds. A MK IX SPIT was at the museum for a while and he made several recordings. The SIW-crew can not be held responsable for any incorrect information nor for any actions taken by others based on this information.
