I could have phrased my post better.  That's true of a lot of my posts.  But, truly, I'm in awe of the knowledge that can be found on all of these bulletin boards.
Actually, long ago, I compared a Colt SAA hammer with my Cimarron Model P because the half cock notch had broken off.  While I didn't take crucial measurements, they seemed to be nearly identical internally.
Best wishes.
