THIS IS A NICE EXAMPLE OF THE ENGLISH WEBLEY-BENTLEY STYLE DOUBLE-ACTION REVOLVER, AS PRODUCED THE LATE- 1850s THROUGH THE MID - 1860s. THESE GUNS PROVIDED LESS EXPENSIVE ALTERNATIVES TO THE ADAMS AND TRANTER PATENT REVOLVERS OF THE DAY. THE SIMPLIFIED DOUBLE-ACTION LOCK MECHANISM TYPICALLY ENCOUNTERED TINTHESE REVOLVERS IS USUALLY OF THE JOHN BENTLEY DESIGN AND USUALLY REFERED TO AS WEBLEY-BENTLEY. A MUST REVOLVER FOR THE WEBLEY COLLECTOR.
