I picked this up at the flea, and then put it back. Have seen far too many rusty Coes wrenches, and this one is far from perfect...
Then i noticed something odd about it and picked it up again. It has a hex shaped ring at the head end of the handle, how odd...
Rubbing it a bit, I saw a digit stamped into the head under the rust, but nothing I could read, but i took a chance...
Turns out to be interesting, it is marked PS&W Co ? / I D E A L / Pat JAN 24 '05 / MADE IN USA
The patent turns out to be for the odd hex ring, the handle on this wrench can be disassembled, the wood is pinned with a screw, and the inner piece unscrews from the wrench's main bar....
