mystery 5/16 wrenches

[BobB]

Can anybody give me any information about these wrenches some are stamped others forged but all 5/16" The only name I cna find if LOGAN on the stamped wrench and " Special USA" on the forged

[bonneyman]

They look like (especially the top and bottom ones) what are called "engineers" wrenches. An open-end design in a size the worker uses constantly, with thick jaws for durability. I think they were used on machinery in factories and such.
I've got one in 1/2" that's really worn. I'm going to clean up the jaws and make it a 13mm with some corner relief for imported compression nuts.

Those are pretty wrenches Bob, just enough junk in the trunk if you know what I mean.

[Papaw]

I agree. The dark ones look like tool post wrenches.

Logan made lathes....

[Papaw]

Logan and South Bend lathes. I saw several Logan references, but no wrenches like those.

[rusty]

Yeah, I didn't realize it was the stamped one, Don't tink there is any Logan lathe chincy enough to come with a stamped wrench.

The top wrench looks like a williams standard set screw wrench, what number is on it?

Also, I seem to remember a comment on alloy artifacts about some company that sometimes just marked tools U.S.
