That deck's in as close to a perfect condition as you're likely to find! Awesome!
This is strictly a shot in the dark, but I'm thinking your deck is probably from the earlier years rather than the later ones of that time span, 1940-1965. Unless the previous owner removed it, the deck wasn't wrapped in cellophane, so it would predate that practice. I just have no idea when they started wrapping decks in cellophane.
