Thanks for the feedback. I frankly will probably just enjoy looking at what is a very cool looking gun. I think you are unquestionably right about the worn ledge as sometimes it will hold in the cocked position but won't fire from that. I have to open the breech and adjust a little lever lip devise to get the hammer to close. I then can usually dry fire it as noted, until it gets stuck again. This pistol shows a lot of ware. It also feels terrific in my hand. Cool gun and I like it cut down and to know a bit about it. Someone long ago in my family treasured this and made changes that suited him or her. Cheers.
