Did all of the older (in this case 1952) Wingmasters have matching serial numbers on the barrel & receiver? The barrel on an older Wingmaster I have has a YY stamped on it, which I believe designates 1952. The reciever is old with the old wood on the stock & the roll grooved forearm. The metal on the barrel & receiver is the old gun metal gray. Someone recently told me the barrel & receiver should have matching serial numbers if made in the early 1950's. Others have said their older barrels don't have a serial number on the barrel. I know some older barrels have serial numbers on them, because I have a 1951 barrel I bought separately that has a serial number on it. thanks,
