"The hammer has been replaced----------------."
I have no way of knowing if you meant that to be taken literally or not, but I'm going to take issue with it. It is inconceivable to me that anyone would take on the task of replacing a hammer. I had a completely redone Colt Officers Model---redone by Walter Roper and his lads----grips, sights, and action job--including the hammer. The most telling comment on the action job came from my gunsmith----old school type-----a very tasteful beard, leather apron, sat on a three legged stool----and smoked a pipe. I'd taken this masterpiece to him for show and tell---showing off under the guise of seeking wisdom. He oohed and awed with great respect, and said, "You know, I hate these *#><ing Colts, but whoever did that action job really knew what they were doing!!"---adding that the hammer was a work of art.The hammer followed the conventional practice of the time, cut off the spur and weld on a replacement worthy of a place in the Louvre Museum in Paris. That's what you saw on the outside. On the inside the most impressive thing is what you didn't see. You didn't see anything resembling any Colt hammer ever made-----and you were pretty sure what you did see would float-----it's that light (comparatively speaking anyway). The big mystery was who made that hammer---------and it's a made hammer, not a modified hammer. The answers offered up to that question followed the usual----none of which made a whole lot of sense when you really think about how you'd go about making a hammer----all except for one. That came from one of THE students in this hive---you know him as Hondo44. He suggested Colt made it----in accord with the design done by Roper. And the more you tried to find fault with that, the less fault was to be found.
So it figures your Triple Lock hammer started life as a Triple Lock hammer----and the parts that fit over the stud, and hook up with the spring, and play nice with the trigger, and hit the primer are exactly like S&W made them. Why would anybody even think about reinventing that wheel?
