Civil War US Model 1840 Heavy Cavalry Saber by Roby

This is a handsome 1864-dated saber that measures 40 3/4" overall, with a 34 1/2" curved, single-edged blade having wide and narrow fullers.  The blade has a bright, pewter-gray patina throughout, with thin freckling along the forte, and within the fullers on either side.  The maker’s marking is still clear and legible on the ricasso reverse: "C. ROBY / W. CHELMSFORD / MASS." with "US / 1864 / A.G.M." on the obverse.   The brass hilt has a mixed yellow-ochre and ruddy-brown patina, while the leather grip has a slightly loose, but intact braided wire wrap.  The scabbard has a darkly mottled plum-brown patina along its length, and is in very good shape, without any dents, and very little wear to the drag.  This is a nice, high quality Civil War saber, by a desirable maker, and is in very good condition overall.  It would make a terrific addition to any collection.
