Dig through a 1960's Drafting Kit with me (or don't, that's fine)

Can we find anything cool? Today we're digging through a late '60's vintage drafting tool kit from Teledyne Post. My neighbor found this in a house that was being torn down, so unfortunately some of the parts are rusted. But we got a ton of compasses, some ruling pens, and some neat drafting templates.
