These early Gillette Techs are distinguishable from later models by the rounded-triangle-shaped slots in the baseplate, as compared to the oval slots seen on later models. Known as Early Techs, Triangle Techs, and Pre-War Techs, they are less common than later models and also shave a bit more efficiently than later Techs.
Right now, we have three available. Two are the relatively common nickel plated Triangle Techs, both in really nice shape: used, but nice and shiny with little plate loss. The other is a less seen variant, a gold plated head with a black bakelite handle. The head has lost a lot of its plating, but the handle is in very nice condition.
