Sisteme Correvon a Morges, .33 cal. under-hammer percussion pistol.  NSN.  Good condition.   3” barrel has very good bore, heavy knurling to allow turn-off for breech loading.  Full length tang extends back from breech with “Sisteme Correvon a Morges, 1854” address.  Smooth walnut stock has few light marks.  Unique under-hammer action works fine.  Very unusual percussion pistol.  Great collector piece!   Antique, can ship to our door.
