Yes bas was right!! I was in a coma by 834!! But not dreaming about pie! That would be the curmudgeon!!He should be sleeping about now. Probably dreaming about pie.
I believe they were ALL walnut until the early/mid 80s when Ruger (and everybody else) started trying to cut costs. From that point forward, I think all of the standard "carbine" models were birch. The deluxe sporter (I believe that was the designation...came without the barrel band and with a checkered stock with recoil pad) was the only one that consistently came with Walnut.The 10/22 stocks was mostly Birch but there was some Walnut through the years...
