tennexplorer, great info, more than I can fathom at the moment. I ran across a triple lock at a local shop and it needs some TLC and perhap I will have a Frankengun project of my own. The problem is that this one is missing some parts. It needs the threaded end of the ejector rod. I have not had a chance to see if such a part is still available anywhere. It also will need a spring of some type as the ejector star falls back if you tip the gun back with the cylinger open. Someone long ago cut the barrel off to about 3 1/2 inches and stuck a rifle sight on it. I just happen to have a 3 1/2 barrel from a 27. The problem is that it has a slight buldge in it. I will look forward to further discussion on this. I need to look at the bore to see if it even needs a new barrel. It's marked 45 A.R.
