I have been following the Cattlemans Carbine thread and I have also been reading about the Colt Walker. In one of the things I read about the Walker they said that some of the Walker sent to Texas were converted to carbines with a 20 inch, I think it was a 20 inch, barrel. I was looking at the exploded view of the Walker and I think I could make a shoulder stock from a converted backstrap. But the big question is does the barrel unscrew? I don't have one on hand to see but does the barrel unscrew from the part that the wedge goes in? The exploded view calls that hole assembly the barrel. If it does I think that would be an interesting project for me and my lathe.
