We went to the Smoky Mountains on vacation last week. We stopped in a little antique shop in Maryville, TN where I bought my first Superspeed restoration project. I found these four, all in excellent condition - a Gem Micromatic, Slim adjustable, ball end Tech, and a Schick injector. A basic cleaning and disinfection is all that will be needed. The Gillettes and Schick are really like new. Picked up all 4 for $50. I was looking in particular for a Tech and Injector, and found the mother lode!
