For sale is a Gillette Fatboy Adjustable double edge safety razor with box and old razor container. This appears to be a 1959 model with E-4 marked on the head. It has obvious signs of use and a nick on the knurling (see photo). I bought this at a consignment shop and cleaned it up, but was never able to make the adjustment mechanism work. The razor still works fine at the setting it’s stuck on. Someone with more knowledge of vintage DE razors might fare better in getting the adjustment mechanism to work. Thanks for looking.
