Please note, standard .45 ACP should not be used in this revolver as it would exceed safe pressures. We always recommend that used firearms are inspected by a qualified gunsmith prior to firing. A qualified gunsmith should be able to give you a better idea of what loads, if any, are safe to fire in this revolver.

The underside front face of the barrel and the underside of the frame in front of the trigger guard are marked “20811”. The cylinder appears to have been marked with a matching serial number, but much of this marking was removed when the cylinder was relieved. The top of the backstrap is marked “N”, the backstrap below this is marked “4”. There are British martial and commercial proofs as well as broad arrows on most parts. There is a rather large and deep broad arrow marked on the top strap. The left of the barrel has the “ENGLAND” export mark stamped.

Our Assessment: P. Webley and Son received their first contract to produce the hinged frame Mark I revolver for the British Government in 1890. From lessons learned with this revolver and from their W.G. line of commercial revolvers, continual improvement in the design occurred, finally evolving into the Mark VI in 1916. About 35,000 of the Mark I revolvers were produced for the British government between 1890 and 1894, including this example. It has had its cylinder relieved for use with .45 ACP moon clips, a common modification on the revolvers which made their way across the pond, though care should be taken not to use loads that will exceed pressures safe for use in this revolver. The revolver is in about Very Good condition as a modified Antique with about 83% of its blue finish remaining. The bore is still decent and the mechanics are fairly strong. This revolver probably has quite a history if it could be told. It could very easily have seen use in any of the armed conflicts and small wars England participated in at the turn of the century. This revolver should be of interest to collectors of military weapons, especially those interested in British service weapons. Please see our photos and good luck!
