Parlor Pistol, .35RF cal. single shot pistol.  NSN.  Unknown maker. Fair condition.  8 ¼” octagonal barrel has poor, rough bore.  Barrel and receiver have no remaining finish with extensive surface corrosion.  Walnut grips are good with extensive checkering, some dings on bottom.  Tip-up action with under lever works fine.  Hammer cocks nicely.  An unusual conversation piece.  Antique – can ship to your door.
