Inquiry (采购产品): Vintage Pneumatic Screwdriver My husband has a very old pneumatic screwdriver made by a company in Michigan. I contacted the Chamber of Commerce in Grand Haven, MI and they told me the company had changed to Gardner-Denver then to Cooper Air Tool in Lexington, SC. I am hoping you might have some historical information! The screwdriver has the following embossed: SUPER Screw Driver Size00R1 NO. 4177 William H. Keller, Inc. Grand Haven, Michigan U.S.A. There are additional numbers on the handle (it looks like a handgun!). If you have information or where I might find more info, could you please advise?
