Latest acquisition is a No 1 sporter , marked on right side of buttsocket with BSA and the piled arms, on the back upper behind the safety is NRF and at the front left of the receiver it's stamped FTR 1953. I can't find any original date , only the FTR date. Would this be a peddled scheme rifle assembled at the BSA factory? During , before or post-ww2? I'll post some pics when I can, plus the barrel knox form stampings, may find something under the black paint (Suncorite applied at FTR?)
