I recently acquired an old Collins monkey wrench. The wrench is in very good condition, so I did some searching to find out more about the Collins company and wrenches. I found a lot of info on them, but some questions went unanswered. I couldn't find out when they ceased manufacturing the wrenches like mine and have no idea of it's value. Apparently, they manufactured a lot of them, so they are most likely plentiful.
Any info would be greatly appreciated.
