dosen't look wide enough in front of the revolving chamber or swept around the hammer like most of the ww2 era colts
Bit hard to tell with the serviceman behinds belt buckle blurring the ejector pin
Appears to have a round barrel so very doubtful a webley
Dose appear it could be a 6" barrel though
As geoff has stated could also be a new century model
Reading through an article and it stated they also produced a 6" model but were generally issued to us troops and not so much allied troops that requested 5" in .38 200 grain slugs
quote "The Victory Revolver was produced during World War II, it is a variation of the Military & Police Model of 1905, fourth change and had the following characteristics between 1942 and 1945:
Barrel: 2, 4, 5, or 6 inch. (4 inch common in .38 special, 5 inch common in 38/200 or .38 S&W)
Sights: Fixed
Finish: Early sandblast blue, sandblast mid-night black (appears grayish black). And finally a parkerized finish. Hammer and Trigger are case hardened.
Grips: Checkered walnut with medallion until early 1942, post February of 1942 they are smooth American Walnut with out medallions. "
