Everyone seems to display H. D. Smith perfect handle wrenches. However, the other monkey wrench perfect handles are rarer. They are all similar to the Smith perfect handle, so from the top in the picture, H.D. Smith, Russwin and two Trimont, a wood handle and an all steel wrench. This may not be correct, but I have been told Smith made a deal with Russwin, and Trimont took over after Smith went down. Is this correct?
