There are a few KF club members who set up and sell parts but aside from them, it's like finding a needle in a haystack. Every now and then tho, stuff does surface so that makes walking the 26 miles of spaces worth it! I also collect prewar Graham stuff and 2 years ago hit the motherlode of literature. I stumbled upon a fellow who set up a card table with nothing but Graham items...by the time I left his space, he was able to fold up the table and go home. My wallet was lighter but I found what I was after!
