Pulled this out of the scrap box, The main bar was so badly bent that the jaw could not move. A couple rounds with the hydraulic press helped some. Then shaving the top edge with the belt sander did the trick. Finished with some gun blueing. This one has patent dates of 7-6-1880 & 7-8-1884. It will be on display for this years 25th anniversary of the Wrench Bar. No "clue" on the little guy.
