Here for your viewing pleasure is Colt New Service .455 Eley (Webley) revolver serial number 126149 which was 1 of 500 shipped to the London Armoury Company on December 26, 1916. It had an interesting service life with British Army markings, presumably Canadian Army (C154) marking and A.E.F. (American Expeditionary Forces) marking on butt plate and if you look closely at the right side grip you'll see what looks like a carved US flag right above the A.E.F. . Photos of rear of cylinder to show Crossed Pennants marking and frame to show Enfield view marks.
