Here are some pics of a Lancaster rifle that has been in the family for several generations. We know very little about it. Family history says it is a .36 caliber "squirrel rifle" and that it was converted from flintlock to cap at some point in time. Barrel length is about 44 or 44.5 inches. Stock appears to be striped maple. The word "Lancaster" is clearly marked on the lock and the maker/mnfg. looks to be something like "R. Buchville" or "B. Ruchville" or something similar. Any ID help, history, or advice about who to contact would be appreciated. Thanks.
