Looking around the safety razor world, there's probably only the Gillette Tech that can rival is ... somewhere at the end of the '30s through to the end of the '70s even in to the '80s perhaps, even then the Tech head continues on the Sterling through to today in some markets.
To say the 1912 design ran from ... well, 1912 well into the '50s if not into the '60s under the Star and Treet brand, outliving the 1914, 1924 and all Micromatics and seeing in the birth of the Featherweights and Pushbuttons, it certainly was one hell of a run! If a retro-run was made today, I would not hesitate but buy one.
