This is a Schick "Type B1" injector. Made for Schick by the Magazine Repeating Razor Company. This is the second model of the venerable Schick injector razor! This type was made from 1927 to 1932. Like the Type As and Cs, the blades are stored in a cartridge inside the handle. By pulling and pushing the end of the razor, the old blade is ejected and a new one inserted. White it is possible to insert a modern blade into these older types, you have to do it manually. The modern injector will not work.
While the bright lights and high magnification show every bit of the brassing, the razor actually looks quite good in your hand. The brass isn't nearly as apparent in your hand. The leather case is in very good condition with no major tears or damage. There is not a cartridge in the razor, but the mechanism works perfectly.
Attractive and interesting piece of shaving history to display, or perhaps even use!
