Thank you for everything guys. I bought the rifle, the trapdoor locks solid into the receiver, so that part is good. The action functions correctly and the bore is decent for a 147 year old rife. Now for the not so good, the screw holding the hammer to it's shaft is twisted off in the shaft. Not sure of the correct term. The firing pin is broken or missing as I don't see it at all in the end of the trapdoor. I also don't see an extractor on the trapdoor to remove the cartridge from the chamber but I really don't know what to look for there. Pictures are beyond my ken.
