If we're suggesting that the rifle has been in some way 'faked' then i suppose it could have, but I can't really surmise why it would have. I doubt very much that such a rifle would be worth a big premium over say, a 'standard' BSA rifle from 1945. It is curious, but I wouldn't have thought it valuable monetarily. That is usually the motive for people to fake things.
As regards the D6E on the rear of the bolt guide way, I have no idea why it is there in Lee enfield's photo, but it is, & I have a stripped reciver dated 1945 that was earmarked for conversion but wasn't, but also bears the D6E. I don't think it has been faked - I have had the receiver in a plastic box in my gun room for at least twenty years & I doubt there'd have been much incentive to create a non-sniper sniper's rifle before that. But then, who knows?!
If H&H outsourced the examiner(s) to BSA later in the production history of the 4T, such that the D6E's were applied at BSA BEFORE the machining took place down at H&H that would explain why we see these occasional examiner marked rifles that were never converted. However, I am only thinking out loud.......... or are they all 'faked up'? Any other suggestions?
