Mass Arms Company Adams Revolver

DR4022. extremely rare Mass Arms Company Adams revolver frame dug many years ago in Vicksburg, MS, there was only approx. 1,000 of these manufactured from 1857 - 1861, the metal is strong with only minimal surface pitting, it has a dark brown patina, amazingly the one piece wood grip is still present and in good dug condition, this is the only dug example I can recall ever seeing
