That hammer on ebay is expensive. The seller has quite a few PA tools at large prices. If I had the bank account of someone with expensive classic cars, then those prices might not bother me. I'm trying to put together enough of the tools for a tool kit for a Pierce Arrow and having some of them...
Do you still have the hammer head? Pierce had their logo put on tools made by Billings & Spencer, Williams, Fairmount, Cheney and probably others. I just joined this site while looking for Pierce Arrow tools. I'd be interested in any Pierce logo tools.
