Klein 3239 Spud Wrench
I agree with Jock. I would add ease of access. The opening will find and slip onto a nut more readily without lifting and placing. I have a few though. I posted a huge Plomb in post #16 on page 1. I got curious and checked a bunch of catalogs. Williams did not introduce a box end wrench with a structural or construction pattern (i.e., colloquially, "spud") handle until Catalog A-409 in 1943. For Armstrong it wasn't until 1957. Plomb in 1939. There are three Woodings Verona catalogs on IA/ITCL. The oldest, probably 1920's or 30's, is not dated. A catalog dated 1949. And a much more modern catalog, guessing 1960's or 70's. None of those offer a box end spud wrench.Wondering why open end appeared to be the standard over box end?
I prefer open end wrenches in general. I do use box ends as well.Just curious. Wondering why open end appeared to be the standard over box end?

Wow. What a lineup!Here's a trove of Bethlehem Steel Corp spuds:
Bonney is a good proximity guess. You might be able to do some visual comparisons. Are there any Bonneys on the thread? I don't have any. I was looking at my Williams, and I have to say, the shoulders, where the rounded handle necks down to the shank, looks different.I'd love to know your thoughts/opinions on this: Who did BSCo contract with to make their spud wrenches?
That's a good idea: do side-by side comparisons (BSCO spuds to other brands). This will give me a good reason to round-up and organize my spud pile.Wow. What a lineup!

Me neither. I was pleasantly surprised.I had no idea that BSCo had a formal Small Tools Department, complete with catalogs.
That book is not available digitally, in PDF or eBook. If it had been, you can be sure I would've posted some excerpts.As soon as I figure out Google books, I'll be reading them for sure.
I'll Give Hagley a call to see if they have the Bethlehem Steel "Small Tools Department" books available for viewing. Thanks for your offer to stop by for a little research if you're in the Wilmington area. So much information hiding out there in seemingly unusual places.Me neither. I was pleasantly surprised.

Google Books, in the spirit of open source and open source foundations that I admire, very helpfully, magnanimously includes printed books that have not been approved for their project in their system, though, and even points you to the nearest sellers and libraries where a print edition can be found. I have ordered a lot of references from Interlibrary Loan that way.
Clicking on that link in this case indicates that Hagley Museum and Library, 298 Buck Road, Wilmington, DE, 19807, has a copy. You might want to call them tomorrow. If it's in their collection and available to view on a visit, I could plan to stop in next time I go down that way, which is fairly often. I would takes notes, and photos, if possible.
That's a couple hairs larger than the differences all my spud wrenches measure between nominal milled opening and spec, but I am going to assume it's the rough nut clearance thing. If you look at the annotations at the very bottom of that table excerpt you attached, you'll see a caveat to that effect. All vintage catalogs have a similar caveat on their structural and construction wrench pages. Some catalogs are much more explicit. Williams, for example, says something about the actual openings being larger by some fraction. I can't remember how many 32/nds off the top of my head, but the difference you are measuring between the opening and the marking and the catalog is probably planned. If not, maybe spread from use, or a little of both.marked "1"
milled opening size is actually 1-3/16"
oddly, the 1935 catalog shows it as having a milled opening of 1"
