I have my 1949 School report in front of me - The Masters just used initials, and some are not that legible, so you can probably help out
Eng Language/Lit = RHW - R H Watts ?
History = RHW
Geography = FHR - F H Robinson ?
Latin = EOJ - E O Jones he writes 'definitely on the downgrade' !!
French - can't decipher, but I don't think it was Cissy Cass
German - again can't decipher
Maths = RS - R Smith
Physics/Chemistry = WmCF = Wm C Ferguson
Art = ABR = A Barron-Renton ??
I'll have a look at a few other years later on
