Yes. And, like many other wrenches made by many other mfgrs, it was adopted from J.H. Williams. That is their model numbering system. Not everyone followed it. Armstrong definitely did. In the 1930's Billings was still marking wrenches with their own numbers, but they would list the Williams number next to their number in a separate column called "Trade No." in the catalog. By the 1940's even Billings had given up and were using the Williams/Trade number as the standard. But there were holdouts. I have Plomb structural wrenches with their 26xx size numbering scheme.Is there a standard for Structural Wrench sizes?
Slightly off-topic . . .Not everyone followed it.
Definitely!Does this look like a hand-forged Wrench?
What he said.Every steel framed project that I worked on only had two size bolts 3/4" & 7/8". I forget the actual hex sizes but I'd guess they were 1-1/16" & 1-1/2" as shown above.
It's one of my Significant Other's favorite finds.Super wrench.

Just in case you or anyone else was wondering, vintage structural (colloquially "spud") wrenches ranged from 7/16" to 2" openings. I have several different sizes in that range, all from the 30's or 40's. I'll try to remember to post a photo later.What he said.

That's an oldie. I'm not a blacksmith but I recently bought a propane forge and have been learning about the craft. I'm guessing how it was made here.Slightly off-topic . . .

Like most people using this Forum, we enjoy preserving bits and pieces of tool history.If this wrench could talk it would have some hardtimes to tell of.
Good idea!Huh! Seems like it's become "Show your SPUD".
Done.If you'd oblige in editing your title into something less interrogative, and more declarative or nominate, and less temporary, more permanent
Wow. That looks like it was left on a railroad rail.Slightly off-topic . . .

You're probably in the best position to determine that, but for one data point, I have never seen a crowfoot angle on a spud wrench before, and for another data point, that model number (907) is for a structural wrench, and again, they had a shallow offset, with a 1-1/6" opening. IF, and again it's a big if, Williams made a crowfoot spud, my hunch is they would've given it a model number like 907-S (for Special) or something like that, and if they were an entire line, maybe a whole new series number. Lastly, it sure looks like they took the offset out of the shank to help them make that bend. Just my $.02.(is this original, or user modified ?)
Well, now that you said I don't want to know why, of course it has made me even more curious! If not mechanical, I am guessing it has something to do with bludgeoning!I want it but you don't want to know why.
You're on the right track. I recently bought a forge to dabble in blacksmithing but the forge is only 1/2 the equation. The other 1/2 of the blacksmithing equation is the anvil and I don't have one. I'm using an old counter weight which I've put a hardy hole in and it's doing the job, sort of. You'll never miss the horn on an anvil until you need to hammer some curves and your anvil doesn't have one (my case). So now I find myself looking at everything that I could utilize as an anvil horn. Lately I've been entranced by the idea of making a bick for my hardy hole which would provide me with a curved surface to compensate for my hornless anvil.Well, now that you said I don't want to know why, of course it has made me even more curious!

Those sizes are correct. Was an iron worker and still know them.7/8 for 1/2 heavy
1-1/16 for 5/8 heavy
1-1/4 for 3/4 heavy
1-7/16 for 7/8 heavy
1-5/8 for 1 heavy
3/4 for 1/2 reg
15/16 for 5/8 reg
1-1/8 for 3/4 reg
1-5/16 for 7/8 reg
1-1/2 for 1 reg
Snerk.(she was not impressed).
I'm going to assume this was a rhetorical get yer goat question, but if genuine, my vote is NEVER!Now.....to wire-wheel, or not to wire-wheel?
AB stands for "American Bridge" initially a division of the United States Steel Corp. They did a lot of the engineering, fabricating and erecting of steel for the construction of USS mills back in the day. They also handled fabricating and erection of a lot of the steel for structures and bridges like the George Washington Bridge, Mackinac Bridge amongst many others. And yes spud wrenches stamped AB seem to draw the most interest, I am assuming because of the tie in with American Bridge/USS.Good solid BS marking, For those who might not know, Post any other marking/stampings the tool may have. It'll prolly indicate company the tool was "borrowed" from. I think ones marked "AB" are the most collected.
