Wooden stock question

Hey guys. I have two model 110's, one is a carbine from the late 1970's and the other is a GLXP3 from the late 1990's. I refinished both stocks with a traditional oil finish and they both cameout looking awesome. The older carbine is lighter in color than the newer model, but I believe both of them are made from birch wood. I know they are not walnut but the question I have is, if there is a possibility for them to be beech wood stocks and not birch? I have a hard time telling them apart at times. I am pretty sure they are birch wood, I am however not sure if Savage even ever used beech wood for their stocks at all. Any help is much appreciated.
