Can anyone comment on the date that the .303" 2.222" tons per etc proof marks were introduced for commercial proofing?
I would say that with a bit of paper stuck on the barrel like that, that it was in private hands before it was exported as opposed to coming from the UKMilitary because a paper patch thinggy looks, well, sort of, er ..., not an Armourers touch!
Rear stock splits were easily repaired and the best option if the rifle is shooting well. Just drill right through from left to right at the place where the wood is at its meatiest then make a slightly tapered oak dowel, glue it and the hole, then tap it in place. Cramp up then make good 24 hrs later and it'll last another lifetime
