This is a nice vintage Gillette safety razor, with the original travel case. The blade box is marked made in US, but the razor only has Reg US Pat. The date code of K3 indicates it was produced in 1965. It is made in the venerable Tech pattern. The short aluminum handle gives this model it's "stubby" nickname.
The razor is in excellent condition. You can see some scratches in the photos, but in your hand it looks pretty perfect. The case isn't so great, but it's holding together and has done its job of protecting the razor. We ran it through our standard "clean and sterilize" process, so it's ready to go as soon as you have some standard Gillette style blades. These are available in a number of brands in stores and online.
Nice little razor for use or display.
