Well it isn't big enough to hang it over the door, but I might anyhow. If I do, it will be lag bolted to the studs for sure. Found this in a flea market this past weekend, along with a few more nice things. It is hefty, jaw opening of 2-1/4 in., is 16 inches long, and flame cut from 3/4 inch steel plate. Then someone with very limited torch ability carved into the jaw. There are traces of Olive Drab paint, and am thinking this is known as a Little Joe wrench. Used for adjusting the track tension on an M-60 Army tank. I used one often enough, I should remember. Next is to put it on a scale. Definitely one of the heavier wrenches I've ever had follow me home. Anyone else have one? Or know for sure about the Little Joe?
