Sweet Find. The Yankee Razor Co. changed their name to Ever ready in 1905 and this looks like a very early model to me. So 1905 1906 I would say. Super close to the Kampfe design as the owner used to work for the Kampfe Bros before starting Gem and Yankee -
Thanks SF, I was wondering since there was no "face" on the underside of the razor, and the manufacturer is listed as "R&S. Mfg Co. NY"
