Percussion rifle, ,50 cal, 40"barrel, looks like a Siler lock, 14" lop, full curly maple stock, wood to metal fit on the inlays is very nice, brass patchbox, really nice toe plate, double set triggers,,,I bought this rifle at an estate sale 15 yrs ago,,it has been hanging in my gun room since,,rifle has not been fired, it is not marked unless its under the wood,,I have not taken it apart,,workmanship looks really good, i think the builder has passed away
