However, I've seen photos where a 21b doesn't have a plug, it has some sort of other contraption that I'm sure involves a spring. I don't know which one you have.
There's a nice write-up on refurbing a 21b here: http://cookingwithjim.com/presto-21-b-canner-refurbishment/
The sealing ring and other parts are still available for that canner, the sealing ring is only $9 at that site, it's also available at Amazon. I'd try a new sealing ring before shelling out the bug bucks for a whole new canner. :)
