Hi from Minnesota, I seem to come across lots of odd, unusual or unidentified tools and hardware that I've been selling sell on E-Bay as rhb-3 for about 25 years now. I hope to pester you good folks with lots of head scratchers. Since I'm here now I,d like to share a recent junk yard find. Hands full of heavy duty ,vintage mechanics end wrenches including combination, check nut style and tappet style. As I began to frantically grab wrenches out of the pile I happened to notice that there seemed to be no visible markings and that the combination wrenches had the boxed end filled solid as if it had been welded shut. Also there seemed to be a lot of the same sized wrenches with some that had rough edges and obvious flaws from forging. When I got home and investigated further I found a few wrenches that were marked with the Martin Tools logo in script. Putting 2 & 2 together I figured that some one had lugged these home from the factory and had probably been passed down to a family member who had no use for them as it all to often happens. The problem with my theory is that the Martin Tool Co. seems to be making new tools that look similar to these with the same logo. So, here I am looking for information on this company and any comments including the value of these kinds of tools.
