W.W. Marston Pocket Model .31 Caliber Revolver. Barrel length 6 ¼”. This is 4th type with fluted cylinder and rounded grip top to frame contour. Very good plus bore. Action works perfectly. Grips have 98% original varnish. Literature on these revolvers would indicate production numbers at 13,000. We doubt these numbers as we have been in business 42 years and sold a great many antique guns and we can recall maybe 8 or 10 of these sold by us. Note: Barrel marked “The Union” which was one of several barrel markings used by Marston.
