I've got one like this... But has original green paint...
I got it from an old man that retired his woodworking shop.
Not super heavy. The jaws are stronger than you think.
It can be your's at a very reasonable price.
Hey great research for me. I really appreciate it.
I knew it was different but I didn't think about the sports field. I was thinking some kind of wood works area(specialized type). Thanks again.
I just got this today & I honestly don't know what these are.... It says "WONDER" on both. And another has "WABA" on the knob.
I'll try to get pics of all angles if I can.
