Wood Chisel Makers and Their Trademarks

Hello All, I don’t know about any of you, but I run across lots of wood chisels with unfamiliar or faded (often both) maker’s marks (m.m.)/trademarks. I’ve spent hours trying to research who made what and when and with what mark – with a lot of success – but still leaving an incomplete picture. For instance, some of you may recal a post and picture of a chisel of mine in another related forum topic. It had an anvil logo that was fading, leaving m.m. indecipherable. Loads of research produced nothing until months later I found a chisel on eBay with the complete m.m., and I was able to go from there. Learning about vintage hand tools in general, and chisels in particular has been a joy -and at times an obsession- for me. What I hope to accomplish with this forum topic is to eliminate some of the unnecessary time it takes to decipher a faded m.m. in order to free up that time for productive research. I hope to do this by compiling a simple photographical database of complete m.m. to be used as reference points for those who inquire, be it myself or another. What I am not attempting to accomplish in this topic is to compile a history of the different edge tool companies or a dating system for the different m.m. I realize that some of this may come as a result of accumulating such a database, but I would like to keep it simple at the start. Feel free to send me a p.m. with such info if you feel so inclined. If you want to participate in this endeavor, all I ask at this point is that comments be kept separate from photographical posts, and that such photo posts include only a brief caption as to the maker. I’m thinking pre-1940 chisels here. I am open to advice and suggestions, so if you have something to add please send me a p.m.
Thanks, and enjoy!
