Hello, Bill,There is an article in Alloy Artifacts, under "Briefly Noted", for Smith & Hemenway, manufacturers & "importers" of various hand tools. They also had a close connection with the Irvington Manufacturing Company of Irvington, NJ. Just food for thought, I am far from an expert, but I am always intrigued by the links between companies, inventors, patents, logos, etc. Regards, Lou
