I thought I had read the lockwork was different from the Colt?
But then I wouldn't know the difference if they were disassembled right in front of me. Parts is parts for the most part.
If I was just in the market for "A" revolver, and had a limited number of dollars to spend, I don't see why they wouldn't do. Even a used Taurus,, not to mention a Model 10/64 cost a bit more these days than the price being quoted here.
Many years ago, I had a Squires-Bingham (the company that morphed inot Armscor) Model 20, 22 rifle. I paid $49.95 for that rifle at K-Mart, and it was one of the best 22 rifles I ever owned. My son claimed it when he got older and to the best of my knowledge, he still has it. I'll have to ask him someday if I think about it.
