The Victory Model was a war finish .38 Military & Police Model of 1905 4th Change. Yours probably dates to 1942.
It uses S&Ws old 'long action', which is noted for having a smoother, more consistent double action pull compared to the current 'short action'.
Your gun lacks the modern internal hammer block safety unless there is a small 's' stamp on the hump of the frame behind the hammer on the left side. A fatality when a dropped gun fired on a warship in 1944 resulted in the development of the modern positive hammer block safety, guns that were retrofitted have the 's' stamp. If not then leave the chamber under the hammer empty.
Most military guns had a parkerised or grey phosphate type finish, if the gun has been reblued it will probably have no interest to a collector. The original grips would probably have been smooth walnut and the guns serial number may be on the inside of the left grip panel if they are original.
In 2006 the Standard Catalog of S&W gave a value of $425 for a very good condition Victory Model, $600 in excellent condition, with a 50% to 100% premium on top of that if marked US Navy on the top strap. Of course, finding someone willing to pay that premium is the hard part.
