This is a terrific vintage model G1 Schick Injector Razor. This type was produced from 1946-49. Right after WWII, Schick returned to the styling of the pre-war E models. The color of the handle is designed to mimic the marbled bakelite of the older razors. As you can see, this is a very attractive set. We've run the razor through our "light clean and sterilize" process, but we left the rest untouched. The blades appear unused, but are included are for display only. As old as the razor is, it still uses the standard injector blades you can buy at the drugstore today!
Unless I can document or authenticate it, I avoid calling something NOS. However, we'll call this one Mint In Box. Everything looks like it's only been removed to look at, and put back. One flap of the box is looser from being opened, but not torn. As you can see in the photos, the ivory toned handle has some beautiful marbling. The gold plating is in pretty much perfect condition.
Overall, this razor looks great and should work even better! Many people think a Schick Injector is the best razor ever made, and the "G" types the best of those.
