This is a very rare and wonderful Collier Revolver. Although initially invented by Artemus Wheeler of Concord, Massachusetts, the successful British patent for the revolver was filed in November 1818 by another American, Elisha H. Collier who operated "Collier & Co., Gunmakers" in London from 1818 to 1827 selling revolving pistols, rifles and shotguns. It is the Collier that is considered by experts to be the first "Revolver" ever manufactured on a relatively large scale. The guns originally had hand-turned barrels, but a few were later designed to turn with the action of the hammer, but were unsuccessful in the field. I am not aware that any of the former model actually exist, but have read of them. Samuel Colt almost certainly saw Collier revolvers on his voyage to England and India as a sailor on the S.S. Corvo. It is known that Colliers were issued in large quantities to British military, and that is where Colt probably got his original thoughts on the remarkable possibilities of a true, single-action revolver. In any case, this is a 100% original example in very fine condition for this model. It is in generally gray to light brown patina with strong traces of original brown finish scattered about its barrel and cylinder, primarily in protected areas. This revolver has a fluted five shot hand turned cylinder and .50 caliber octagon barrel and automatic primer. The barrel has a fluted top strap and an under rib with a single iron ramrod pipe with German silver bead front sight. The pistol has a squareback iron trigger guard and a walnut stock with finely checkered grip. The top of the barrel rib is engraved "E. H. Collier, London" in Old English script. "E.H. Collier" is engraved on the side of the lock plate in Old English letters above "18 PATENT". The revolver is decorated with well executed scrollwork on various parts. The bottom of the trigger guard is engraved with a stand of arms and detailed borders. An eight-pointed star with a flower in the center is inlaid on the left flat. English proofs are present on rear of cylinder internally. This is a very rare and very fine condition Collier. No Revolver Collection that spans models from beginning to end that touts itself as being complete should be without one of these rare revolvers.
