Might come in handy someday.Thanks. It looked interesting, so it has a new home
Old railroad tools are really cool in my opinion. I'm partial to them because of my family history associated with the Erie railroad.
I'd be celebrating that find. Nice grab.
C&M Chicago and Milwaukee Railroad valve wrench
https://www.ebay.com/itm/Lot-of-4-V...764136?hash=item4d9c6b5ee8:g:Cq8AAOSwtoBdhpfL
So do you maybe have a reference a little more convincing than an ebay link? Was the Chicago Milwaukee & St Paul Railroad even historically connected with the Chicago & Milwaukee Railway? ...I guess it wouldn't matter if you're just showing Railroad wrenches with similar initials as an example but the wrenches aren't a match either. Do you have examples of the the wrench style in the original post to this thread that are conclusively railroad wrenches that you could link to? Also, is there a specific "valve" you talking about on the train. Thanks.
My post was as neutral as I could make it but apparently It wasn't enough. Someone might assume by your snarky/sarcastic, overly defensive response that you don't have any additional evidence. That doesn't mean that you're not right. It also doesn't mean that you can't site your sources...though it would have been better if you did. It's common on these boards to ask for or expect a little evidence or a line of reasoning behind opinion stated as facts. I obviously didn't say all RR wrenches should look exactly like the ones in that ebay link you posted, and it's not crazy for someone to know a specific application for a wrench.

Bro that headscratch icon is fitting....If I told you what time it was would you expect me to explain the specific tools the watchmaker used to repair my watch?![]()
Empty Pockets,
What is the OAL of the wrench? And what are the openings?
It looks awfully short to be a RR wrench to me. Also, the ends are forged onto the shank with strange angles. And thirdly, it has the reinforced jaws more characteristic of machinery wrenches, tool post wrenches, and set screw wrenches.
The term "engineers'" wrench is attributed to power engineers (stationary or traveling, i.e. locomotive) and an engineers wrench is characteristically much longer with 15* angles. Prior to early 1900's it didn't even exist on engines or in roundhouses, when the only wrenches were monkey, pipe, screw, which were known to break, or alligator, which were known to round off nuts and ruin brass fasteners. Blacksmiths forged fixed wrenches as replacements for engineers and machinists.
Just my $.02. I could be wrong. It could be an anomaly.
The one possibility that jumps to my head for machinery wrenches is Curtis & Marble in Western Mass., which is in your general part of the country, too. But I don't know. They didn't make wrenches for sale, and I am leery of the fancy cast- or forged-in letters for an in-house wrench. So I am not totally sold on that, either.
EDIT: I take back that hedge. It was customary for outfits like Curtis & Marble, Crompton & Knowles, and others making machines for the textile industry to ship them out with wrenches for turning set-up and adjustment nuts. I have some.
Cool find either way.

Lots of references in Google books, can give you age when they existed, plus minus about 10 years. Might find something useful by digging in, but I gotta walk the dogs.Do you know anything about them? Information is scarce
Mainly trying to see if its worth trying to sell haLots of references in Google books, can give you age when they existed, plus minus about 10 years. Might find something useful by digging in, but I gotta walk the dogs.
Unless someone is building a cotton mill, I’d say not gonna be much interest.Mainly trying to see if its worth trying to sell ha
