Thanks for the response. This one is an early second model judging from the latch you described. Based on that I would say it was made in 1895. It's still an interesting gun and I'd like to go ahead and fix it up. I'm a reenactor and do a little gunfighting now and again. I have a friend in Granbury who is a gunsmith. He builds flintlocks and can help me with repairing this. The cylinder doesn't lock tightly when you pull the hammer. That's why I want to replace it. Other than that I can work up some black powder blanks for it and go have some fun! Thanks again! While I'm at it, have you ever heard of a manufacturer called Hy Hunter Arms?
