This is a conversion from percussion to a Trapdoor 10.4mm rifle. The mechanical function is very good and the bore is very good bright and shiny with strong rifling. It retains 65% finish and the wood is fine except for a chip from the toe. This one is missing the cleaning rod but Dixie Gun Works or S&S have replacements. This one is marked S.J.G. Neuhausen on the lock top.
