I love collecting single ring razors. I recently acquired this 1914 single ring (based on serial number). The plating is good, the teeth are good, there's no cracks in the handle. The patent date is on the tube as should be. What is interesting is that there are no other stampings on the underside of the baseplate. While I know this can occur with earlier single rings, I've never seen one this late without stampings. Anyone have any knowledge or thoughts on this?
