Hay Lou,
I have three of them fellers, back from when rumor had it that there wouldn't be any more. Well worth the price of around $160-190 on sale at Dunham's. Only problem I had was a chipped firing pin that still works, but haven't been able to find a replacement. Not a beautiful piece of machining but works every time; I shoot only Black Powder and don't clean it as well or as often I should, it doesn't seem to care. As said above, polishing the chambers helps for paper hull extraction, but brass falls right out.
I have a couple other doubles without hammers that I never use any more.
