Rare bag-type powder flask with lanyard ring, manufactured by Dixon & Sons of Sheffield for British proofed Colt Model 1862 Police or Colt Model 1865 Pocket-Navy percussion revolver or English percussion revolvers with similar calibres.

The brass circular top is stamped “JAMES DIXON / & SONS / SHEFFIELD”. This flask, even-though it does not say “COLTS POLICE FLASK” is for the Colt Model 1862 London Police percussion revolvers and also the Colt Model 1865 Pocket Navy percussion revolvers that were shipped, circa 1862 to the early 1870’s, to Colt’s London Agency at 14, Pall Mall.

The three-position Police charger on this flask is 3/8, 4/8 and 5/8 drams (2/8, 3/8, 4/8 for the Colt Pocket). The end of the charger is chamfered, to accept the chamber of the cylinder. The brass top is polished, with a fire-blue spring. The body is a dark brown / red lacquer. Very good condition.
