Sadly, aircraft at OTU's didn't get much photo-coverage, but I'll have a look to see if I can find anything.
Wellsbourne Mountford is still in use today, as a civilian light aircraft field. Back in the early 1980's, there was talk of creating a British wing of the then Confederate Air Force (now Commemorative AF), and it was thought that Wellsbourne would have been the base. The nearest they got, as far as I know, was a Harvard based there.
