Thanks Grant. The chap with the 'iron Cross', in flying kit, is in fact Major Brandle, RK, apparently inspecting damage to the engine of his '109G. (nb - I can't find an umlaut on the forum 'system' to place over the 'a' in Brandle !).
Just out of interest, the quickest I've ever taken an engine out of a car, was around 15 to 20 minutes. This was back in the 1970's, when I used to rally an old Sunbeam California (the 'fast back' version of the Hillman Imp, rear-engined.).
Actually removing and re-fitting the engine was easy and quick, as it was held by four bolts, and two in the rear body cross member, which acted as a rear engine bearer, and the engine could be supported on a 'trolley jack', unbolted and moved back, out of the engine bay.
Unfastening all the connections was relatively quick also, and from start to finish, when removing the engine, only took around one to one and a half hours. Once bolted back in place though, re-connecting everything was a b*st*rd, taking twice as long, which meant the whole process, from start, to removal, to replacement and engine running again was around 4 to 5 hours at best - and that's on a small 'lump', at ground level, in a warm, dry, garage !!
