Greetings and my apologies for dropping in here without having first lurked for a time. Someone in another newsgroup suggested you folks as a likely resource for information on something I stumbled across.
I am a welder/heavy equipment mechanic by trade but I do some hobby level blacksmithing as well, so my eye is always open to unusual metal working tools.
A couple of days ago I found a hammer which had "Bell System" stamped on one side. There are no other markings on it. It's about 3 to 4 pounds, a straight peen and the really unusual thing about it is a 7/8th inch hole through the head, parallel to the peen and handle.
Would any of you happen to know the purpose of that hole?
Again, my apologies and thanks for your patience with an out of the blue drop in.
