This is a rare example of an early powder flask furnished with the First Model Colt Dragoon revolvers featuring the plunger spout and a similar design to the Colt Walker flasks. It measures approximately 7 1/2 inches long (excluding spout) and features a brown lacquer finish and double face design. The design is a stand of arms motif with flags, pole arms, and artillery pieces above crossed Colt revolving rifles and revolvers. At the base is "COLTS PATENT" in a banner. Triangular carrying rings are positioned on the sides near the base. The plunger is marked "35/GRS" and a "W.A.T" inspection mark is stamped below. The ball compartment gate is stamped "COLTS/PATENT" in curved lines. Another example of this type of flask is pictured and described on pages 162-163 of "Colt Percussion Accoutrements" (1994 First Edition) by Robin J. Rapley with the parallel markings on the ball compartment lid. Provenance: The Greg Lampe Collection
