I stopped by a few antique shops today at our house in Arizona and came across these three Gillette razors. They wanted $110.00 for all three so I offered them $70.00 cash and all was sold to me. All I did when I got home was clean them with hot water and anti bacterial soap scrubbing them with a super soft tooth brush and then dried with a soft micro fiber towel. After this I soaked them in Barbicide for the appropriate time rinsed and dried. Now they are shave ready and all three work flawlessly. Also the insides of all three razors were flawless no corrosion issues after cleaning. See all three pic’s. * 1st razor Gillette Slim date code J-4 1964 * 2nd razor Gillette Super Speed code X-4 1952 * 3rd razor Gillette Black Tip Super Speed the one with the SS thin shim between the black aluminum knob and the handle code X-3 1952 See before and after pic’s, Happy Shaves, Bill G
