Stan, you are a very lucky guy! I have 2 of Mr. Schillinger's beautiful locks. They are simply the best percussion locks I have ever seen. Every part made of the finest material and polished to the highest degree. Fitted perfectly and they deserve to be mounted on the best gun possible. One is for a 1 inch barrel and the other is for a 1&1/8 inch barrel. I bought them 40 years ago and still have not seen any better. His triggers and rifle sights were also of the highest possible finish. That "old man" could really make something!
