Iver Johnson wrench

[JoeCB]

Just found this nice little wrench at a garage sale. I spotted the "Iver Johnson" name that I associate with firearms. A little research found that they also made bicycles and motorcycles, so I guess that this is a bicycle tool. Any idea of the vintage?

The June issue of the MVWC Newsletter reprinted a couple July 1917 hardware trade "new product" announcements showing this wrench, a "screwdriver handle end" wrench, and a loop handle screwdriver.
