Dating between 1933 and 1935 (National Recovery Administration was only active during those years) this is a GEM Micromatic twist to open safety razor. During the 30's and 40's GEM along with Schick were the only real competitors in the marketplace for Gillette.
This razor comes with the original box and looks to be very little used. No rust or corrosion and lots of shine to the chromium plating. Also comes with 6 GEM Blades in their original wrapers. This would make an excellent additon to your vintage shaving collection and is a very nifty historical piece.
