That's an Armstrong 1-1/4 inch single-head open-end wrench. It's just under a foot long and at least twice as heavy as my Exhumer 9.
Chicago-based Armstrong Tools has been in the manufacturing business full-time since 1900. The age of this particular wrench is a mystery to me, but judging by its condition it's been around for quite a while. I snagged it for five bucks at a garage sale some years ago. (Today's equivalent will set a buyer back about $40.)
MADE IN U.S.A. is clearly visible on the head of this wrench, as it is on current-production Armstrong tools. From the company's website:
"Armstrong Tools are still, and will continue to be made in the U.S.A."Now, please permit me to introduce the elephant in the room: Mrs. KintlaLake doesn't expect to do any wrenching with this wrench, any more than I'm likely to be prying stuff with my pry-bar.
To be clear here, we tote these tools so that we have something to swing in an emergency. The purpose may be self-defense or escape. The target may be an attacker, or it could be the window of a burning or submerged vehicle.
In a wilderness-survival situation, the primary field-expedient weapon is the club. My missus and I simply are applying a variation of that principle to everyday life.
