Picked this up on the way home. At first I thought it read GM & D Co Chicago. No luck with a quick search. Tried C and O as well as the first letter and about the same. I'm sure one of you guys knows what it is.
Also it has C6 on the back I am assuming designating the 6 inch overall length.

nice 1.

Just a WAG but could it be Gulf, Mobile & Ohio Co. as in the railroad. I say it's a WAG but I did see an open end wrench in an antique store the other day marked FRISCO that was around 3 FEET long so a 6 inch adjustable may not be out of reason for a railroad. Tighten them packing nuts on the steam valves. I know just a Newbie guess.

It's possible but I am fairly confident the third letter is a D. Also the few railroad tools I do have are stamped initials on a production tool from another company, but that probably wasn't always the case.

Looks nice!

The initials match "Chicago Manufacturing & Distributing Co." - the company that made the "Wright" ratchet (http://www.datamp.org/patents/displayPatent.php?number=1089737&typeCode=0 ) . But everything known to have been made by that firm was malleable iron & this wrench appears to be forged -- a consideration which argues against that company being the maker. Needs a lot more research to reach a definite answer.

Beefy little thing. How long is it?

They held patents for forging dies so I'm not so sure that's accurate. https://patents.google.com/patent/US1355434A/en?assignee=Chicago+manufacturing+and+Distributing&sort=old
My 99% bet is that you are right, Chicago Mfg. & Distrib. Co.

It's about six inches long with the jaws being nearly 7/16 at the base. The Chicago Mfg. and Dist. seems to fit it appears they did some forging http://alloy-artifacts.org/chicago-mfg-company.html#chicago-mfg-speednut-1830033
