I have one of these in my collection.
I can't give you a firm date, though I believe it to be prior to WW-II. This was a common style of adjustable wrench, aka
Monkey Wrench, before the
Crescent Wrench (modern 30 degree offset adjustable wrench) displaced it. These wrenches usually had longer handles, and the smaller bicycle versions were made for convenience and qualify as the "mini-wrenches" of their day.
