In my experience, and it is never an exact science, the prefix letter or letters on the Victories is usually to the left of the lanyard ring with the number to the right in entirety. Flaming bomb before the prefix letter or letters. If that helps. Some did not have the flaming bomb on the butt, but on the left top strap before the property mark. The Navy marked examples I have seen are at times a law unto themselves, would not expect to see the flaming bomb symbol on them as they are army markings. The V plus serial all in one hit to the right of the Lanyard ring is new to me, you learn something new every day. Others with more knowledge will chime in soon I am sure, good luck, sounds like a nice find.
