Edearman, you have a S&W victory model. These were usually a four inch barreled .38 special revolver based on the K frame, made between 1942 & 1944 in a serial range V1 to V769,000, when a change to the hammer design was implemented.
Many guns were made for the British Commonwealth under the lend lease scheme using the same serial range but chambered in .38-200 (.38 S&W) with a five inch barrel. I have read that some of these were re-imported into the USA and the cylinders bored to .38 special for resale. Check your pistol to see if the chambers have a slight taper at the extractor end, or if it has been overstamped to .38 S&W Special. If it is a conversion then it may bulge or split cases.
SCSW3 values as follows: ANIB $750, Exc $600, VG $425, Good $365, Fair $275, poor $135.
The victory model was built on the square butt frame, but with small grips by today's standards. If you have a genuine round butt gun then it us an oddity and may be worth more to a collector.
