Hubert L Harrison: If your gun is in .38 S&W special it is a .38 Military & Police Model of 1905 4th change. If in .38 S&W then it is a .38/200 British Service Revolver (Model K-200). SCSW gives the serial number range 700,000 to 1,000,000 for the period 1940 to 1945, with the 760,000 range being used in 1941. Because the V prefix for government contracts was introduced in 1942, with 1,000,000 guns produced by 1945, I am inclined to believe your gun was made in 1942, although it may have been produced later as as a gun for commercial sale.
If the nickel finish is original then it will command a premium over other guns from this period.
Many of the British guns were converted postwar to fire .38 S&W special and resold into the American market. Check to see if the rear of the chambers is oversize. If so then only shoot standard pressure loads through it.
