Got this hammer along with the Charles Hall & Co. mattock behind it and was curious on the age so I looked it up. Handle and red paint was someone's home job, even painted the steel wedges and not a spot on the handle or at least what's left of it since it's taken some overstrikes. You can probably guess the issue finding info on it though. I found a few examples of the same marking on some 16oz and a different font with Bridgeport on the other side but generally just a bunch of 20th century brands and not the 20th century brand. Curious if anybody knows about the brand and where the thumper handles came into play. Can't find anything on why the thumpers were made however I do use a 4lb sledge thumper for woodwork.
