I picked up the other stock about six months ago, when a large lot of estate stuff (ammo and accessories), including Carbine ammo (which I also snagged) came in. We do lots of firearms and accessories from estates at my shop I work at. Well, I did some detective work this weekend, and found out that stuff was actually from the same estate as the carbine recently came from! We did not get the guns initially, as the family was not ready to sell them until everyone had an opportunity for a pick. Makes me wonder if it is the correct stock for the IBM. The Winchester stock is near mint, and the guy may have put it in it because it looked nicer. If it is the correct stock, I'll have a minty Winchester stock to sell.
