Welcome to the forum. You have pretty good dating information already -- early postwar, say late 1945/early 1946. Over 800,000 Victory models were produced between 1942 and 1946, so there is in general no scarcity premium. However, some models and some serial number ranges are in demand among varietal collectors, and the early postwar guns seem to have a certain appeal. Condition boosts value. An ordinary early postwar gun in worn but usable condition may be $300-350. In top condition (finish well preserved, fired very little) you might reasonably value it up to $500.

Others will have other ideas. If you average the value ranges that are suggested to you, that number will probably be pretty accurate.
