Assuming the stocks are original, and you said the number from the butt and inside the rt. stock are the same, so they are, your gun was manufactured sometime round 1930-1932. It is too early, by several years, to be a Victory Model.

I have to assume the caliber marking is .38 S&W Special CTG(?) as SCSW makes no mention of the 1905 4th Change being chambered for the .38 S&W (.38-200) until the British contract guns beginning in 1940. It may have been re-barreled with a .38 S&W barrel, but not likely. As with the stocks, cylinder, extractor and yoke, the barrel should also have the serial number stamped on the bottom flat under the extractor rod if it is original.
