If you measured correctly, I "believe" it to be from 1964. If you do plan to sell it, I would get a letter from Taube and put it in auction. If you're keeping it, I would just leave as is.
But, I will also add that just because it meets specs for that time period doesn't necessarily mean its a Mantle gamer.
