Hopkins & Allen Falling Block, 12 ga. single shot shotgun. NSN.   Good condition.  30” steel barrel has clean bore with very light pitting.  2 ½” chamber, choked CYL.   Barrel and action have little remaining finish, turning patina.  Walnut stock and forearm have very good finish and checkering.  Smooth steel butt plate.  Action is tight and works fine.  These have usually had a hard life - this one is nice!   C&R OK.
