did not find much, a version of that drop forged instead of stamped, with a gear operated jaw, , a hint they made jar wrenches(??)....

MVWC shows one like yours...

Apparently patented, but i dunno what patent....

Last one on ebay went for fair money....

EDIT: Patent on datamp: http://www.datamp.org/patents/displayPatent.php?pn=2361607&id=24893

Also, from the us patent I found a Canadian patent, issued May 29,1945

'Least it gives you a date...

Odd, I found in fact, 2 canadian patents for pliers, so I assume there is another us one somewhere...

CP 351917 issued 7/30/1935 For a weird slip pin cammed plier
CP 427738 issued 5/29/1945 For a geared handle plierwrench (The datamp one)

Seems like there should be at least one more patent here....

Heelspur, does yours have a sliding handle or a rotating handle???

Also, canadian patents, like english ones, included occupation of the inventor, who lists himself  as 'Blacksmith'....

It slides, and has 3 teeth on the side w/the top jaw and 5 maybe 6 teeth on the lower jaw.
