A friend inherited this revolver with a bunch of other guns. It was very hard to cock so he brought it to me to check. I guess it is just worn out in the hand slot because of heavy use over the years on the brass frame. Here is a picture of the hand at half cock and the slot chimney base was protruding out into the frame. After peening it back flush it cocks a bit better but is too far gone to be reliable. Just the problem with a brass frame after a long life, I guess.
