I had posted this in the garage sale thread previously.
I am not too successful with search, so hopefully this is interesting to someone else & has not been beat to death.
The tool was rusted & frozen when I got it, it took PB Blaster and a lead hammer to work it loose to clean up.
I found information on the Grace's Guide site:
The wrench is machined and has a split screw that engages a captive ring nut similar to pipe wrenches.
The small flat head screw is used to limit travel of the jaws & needs to be removed to disassemble.
I have included a 1929 catalogue scan from the Grace's Guide site.
several other of their tools pictured have a similar adjusting design, (or so it seems to me).
The wrench would be a bear to use compared to the ease of adjusting a standard Crescent style design.
On the plus side, there is zero flex in the jaws. Once tightened down on a nut, it will hold fast nicely.
