I actually bought a wrench yesterday at a swap meet in Marietta Ohio. Never seen 1 like it b4. No markings on either side. Seems to be a fits all sort of wrench. Maybe hamemade? Had to have it. It was in a box of stuff marked $5.00 Maybe it'll help me out at some point. Or not. Lol. Any info if someone knows something about it, would be appreciated.
