I picked up this wrench at a grarage sale recently. It is marked "Patented", "Forged Tool Steel", "Made in USA", and "Marshalltown, Iowa". I think that the Marshalltown connection means it is a Hawkeye wrench, but all the ones I can find are simply alligator wrenches.
The photos show it next to a Cornwell 3/4" deep socket that was in the box, along with some HF junk from China and some interesting vintage American tools.
It is a monkey wrench with a hammer head built in, and the opposite end is an alligator wrench. It has seen some hard use, but functions properly.
I'm guessing that it was made toward the end of the Alligator era and that the monkey wrench end got the most use. I suppose that Hawkeye was trying to change with the times.
Anyone have more information? This will be a good wall hanger, as it is so interesting.
