I would also add to keep your eyes peeled at gun and knife shows, as well as some of the auction boards, big and small.
And don't be afraid to ask or tell people what you're looking for.
I happened upon mine at a killer deal from a gent at a gun and knife show who apparently didn't know what he really had. He mentioned something about a "Busse something or other", and calm, cool, collected, but jonesin' on the inside, we struck a deal.
They do turn up, and when one does, act pretty quick, as I don't know what kind of numbers or how often Jerry made these, but they do seem rather scarce.
