This is a vintage three piece silver colored Shaving Safety Razor with a Three piece design, top blade holder has one threaded prong (for handle). Inside: "PAT. NOS. ON PACKAGE", underside: "REG. U.S. PAT. OFF. | [Gillette diamond] MADE IN U.S.A." According to Badger & Blade I found it is from the late 1930s. It is well used with some tarnish and plating loss. Some the newer blades are made for use in these older double edge blade razors. I am including a sealed box of Gillette Blue Blades with 5 Blades. It was cleaned and polished.
