it's a King 613 or 615, a student model derived from the Cleveland Instruments, these saxophone's company was bought by King and used to produce cheaper instruments, the market really doesn't like them, so they are worth very little but they are good players. Their serial numbers follow the Cleveland Instruments serial number and NOT the King SN. In my part of the world, even if in pristine state, you can buy one for 150€ .
I thought you stated on another thread that it was a Zephyr. It sure looks like a Voll true series II but you need to look at the engraving. I think that the Zephyr started around 180,000 so yours should be a Z. It really doesn't matter that much since the VT II and Z are pretty much the same.
Also you should try to keep your posts in one section as the admins here don't like cross posting.
You will enjoy this alto once you get the kinks out.
