Found this in some estate sale junk:
Nice find! Relative to Farmer J.'s cogent observation...
It has a similar look about and mechanism it to those 'Speednut and others' wrenches,
...does it self-adjust? When you hold it by the handle and turn it to and fro, does the dynamic jaw open and close?
If you search Google or better yet, Google Books, on American Rolling Mills Company or ARMCO, which made steel, from pig iron to finished products, and later changed their name to ARMCO Steel Corporation, you will find all kinds of references. The "NEW YORK" must refer to a branch office, perhaps a mill, because the first and main mill, the HQ, and the research office was in Middletown, Ohio.
I don't know if ARMCO Products was an offshoot or a different entity. My guess is offshoot.
