If you’re going to punch holes in 3 x 5″ index cards for your new library card catalog and want something to match your 20 gauge office furniture, you really ought to have an era-appropriate hole punch. Presenting the industrial strength Mutual Centamatic Punch No. 250 (Made in Worchester, Mass. U.S.A.), which I picked up today at the local thrift store for $0.75.
@chrisaldrich Either way, it’s a cool device.
I have a Mehrfachlocher Leitz Vario-6 5026 still in use. The problem is to handle it correctly since I have lost the manual years ago. Despite that fact a gadget which I mention in my own forum.
@chrisaldrich nice! looks like you got a great bargain!
