One Big Spud Wrench! Does anyone know anything about it? 39.5" x 10" x 1"

[UncleBill]

It is stamped on both sides 3692998 Erector Link Wrench. 39.5" long, 10" wide, 5" jaw opening, 1" thick and weighs approximately 11 pounds.

I really am hoping some of you all can help me on this. Where it might of been manufactured, use, year, and anything else.  I basically found it at an estate sale by Pismo Beach, CA on a vast property that had a multitude of buildings and trash.  The sellers didn't know anything about the history of it.

I didn't find anything on this wrench at all.

 I wouldn't call it a spud wrench because of the blunt end and hang hole.

Thanks for trying to check.  I also checked and hit all dead ends. So hopefully someone on this site will know something.

Probably for working on a steel erector.

Probably NOT for Erector Sets, unless they were manufacturing them in sizes of which I was not aware.

seen a wrench some time back can't remember the sizes but it was big and heavy found out it was an oil field wrench

[UncleBill]

It's odd that something this size doesn't have some kind of manufacturer mark on it.

I am curious to see the 5" bolt head or 5" nut head.  Can't seem to find one of those on the internet.

If it was manufactured, I would guess OTC. Their adjustables have a similar shape to them.

Hello, I am guessing dairy or agriculture tank wrench. Regards, Lou

A  4" I.D. Nut, 4" tall, 6" wrench required, suppose be for some kind of anchor bolt application, or bridge,tunnel etc.  just over 20 lbs.
