You are in luck (like you weren't already getting such a great find). My 1967 catalog shows the cabinets on page 4 and lists all the parts and part numbers. You could buy the Diamond parts or the Diamalloyparts, and you could get the assortments in a cabinet or pasteboard box. Send me a PM with your address, and I will send you a photocopy of the page.
I will try to post the pic of the page here later, but I am in the middle of a large tool cleaning project. I bead blasted 20+ boxes of tools yesterday (about a half a ton; I think it is a new record for me). I am getting ready for a tractor show in July in NC.
