33″ round barrel 54 caliber. Lock date is 1848. There is quite a few different markings on this gun. Carved in the wood on the stock is “ACA” and in smaller letters “csa”. Metal is mostly a greyish and has been cleaned at some time in the past. Wood is in relatively good condition with numerous dings and scratches which is to be expected and one minor crack just down from the rear sight. This is a fine piece of history.
