keeps growing! Just got this piece. It is a Colt New Service made in 1916 for the British government. It was originally chambered for the .455 Eley round (standard British revolver issue) but has been re chambered and re proofed for the .45 Long Colt cartridge. The Long Colt is, of course, much easier to find in the States and is a much more potent round. The grips are not the original military ones. They shoud be plain walnut without checkering or emblems. Getting the grips put back correct should not be much of a problem. I think it looks pretty good for a 95 year old piece! Also, has British military unit markings on the butt by the lanyard loop. Should be interesting to determine to what unit it was issued.
