I get it now; your SN is 957K - I misread it at first. Victory SNs stopped at 811119 in August of 1945. Obviously Colt was still making them post war in the S/W caliber for the civilian market, maybe with left over U.S. Property frames?
Parkerized finish is in great shape.

The Victory model was so named for the "V" prefix which was placed before the serial number and represented "Victory" against the Axis powers in World War II.
Serial numbers for the .38 special Victory model began at about V1 in early 1942 and ran until VS811119 with a date of late August of 1945 (end of production). V1 to approximately V39,999 were predominately .38 S&W Caliber (I have observed revolvers in the 1-40000 range in .38 special caliber). Serial numbers are located on Inside right grip, frame butt, Cylinder, extractor star, and bottom of barrel. Crane and crane recess are also serial numbered to each other, but this is a different number then the revolvers serial number as is correct for Victory model revolvers.
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.
