Ran across this deco circa 1933 Schick Type C1 "injector" travel razor the other day at a flea market and couldn't pass it up...just a really beautiful, well made, and neat little design.
Removing the end cap from the case reveals the shaving head which is on a pivot -- it is swung ninety degrees into the shaving position.
At the other end of the handle are two "pulls" -- one marked "blade" and the other unmarked. Pulling on the unmarked "pull" ejects a "magazine" marked "REAR" on the its outward facing surface. The user fills the "magazine" with blades, pushes the "magazine" back into the handle and closes the "pull". The "magazine" stores blades in the handle.
The second "pull" is marked "blade". It is actually one end of the "injector", which acts like the bolt on a "bolt action" rifle. When the shaving head is in the storage position -- i.e., in-line with the handle -- the user slides the "pull" out of the handle then pushes it back into the handle. This pushes a blade from the storage magazine out through a slot at the other end of the handle and into the shaving head -- in the process, ejecting the blade that might be in the shaving head. The user then rotates the shaving head ninety degrees, and the razor is ready to use.
I also picked up a little Benrus watch from the same vendor, $13 for the pair....a nice way to start the day.
