I can confirm seeing 2 at Sibson. I can also recall seeing some Varsities at Little Staughton undergoing overhaul in one of the hangars in the late 1960’s.

WJ916… It would have been taken in the early/mid ’60’s I think. I went to so many shows in those days, it could have been taken anywhere south of Coventry and east of Brize Norton! I didn’t scribble on the back of the pic either, so can’t be sure.
I bet AJB knows. He was always at the same shows as me.
