Need ID on old PA long rifle
 

Anyone know anything about an L. LEMAN Lancaster, PA long rifle? A friend of mine has one and would like some information about it. He found it hidden in an old home he purchased 40 years ago. It is percussion cap; full stock (Tiger Maple); double set triggers; engraved with Silver inlay (rosette) and Silver patch box cover.
