This flask measures 8 3/4 inches in length. Both sides relief decorated with the "Trophy of Arms" motif and with "COLTS PATENT" banner at the bottom below crossed revolvers and revolving rifles. Near the spout it also has Captain William Anderson Thornton's script "WAT" inspection stamp. He was an inspector from 1840-1861 and inspected Colt Walker and Dragoon revolvers along with a great many other arms. His mark has been found on original Walker and early Dragoon flasks. The top is correctly secured to the body with three steel screws. The plunger charger is marked "GRS." It has the correct rounded oval markings as opposed to the later parallel markings. The lid to the ball compartment is marked "COLTS/PATENT" in an oval. As noted in "The Complete Collector's Guide to the Identification of Colt Percussion Accoutrements, 1834-1873" by Robin J. Rapley, "This Colt stamp is otherwise found only on the Walker single, double and gang molds, the first (approximately fifty) Whitneyville-Walkers, and a few early Dragoon flasks made by Dixon." It has the crossed revolvers correctly left under the right, the truncheon pin on the mortars, and inline mortar rings. The latter two indicate it is not a Walker or Whitneyville-Hartford Dragoon flask. The triangular hanging rings on each side near the bottom as were personally requested by Walker.

Fine with a mix of 75% plus original finish and aged patina. There is a small crack by one of the screws on the collar. The designs are soft but clear which is appropriate. There are some minor marks and scratches.
