Hi Denis, I think the Varsity picture you have was used as a development platform. The names you mentioned Ernie Dunsford, Dick Barton and I presume Bes Bye AFM where members of "C" flight 51 Sqdn and I seem to recollect that G Ayres was a member of the Electronic Warfare Avionics Unit (EWAU) at Wyton and the painting may have been presented to him io his leaving, but it's only a guess. I don't understand the date you mention (1948). I was a member of "C" flight from Nov 1968 to Aug 1983.
Regards
D Prout
