I know we've gone off thread slightly here - surely the tracks on the hangar floor were to put the Mk 3 Shack (the one with the nosewheel) in sideways, 'cos the tail was too high to fit under the roof trestle unless the nose was raised. It was certainly a 42 Sqn hangar (Mk 3's) when I was there in the late 60's. Although I also vaguely remember an ancient (to me then) pilot mentioning it was for Liberators!
NB Had plenty of flying time in 795 as well, so hope she can be saved. With a bit more money that could be two MPAs available (795 and 963), assuming they could retro fit with ASV 21!
