I got this in a box lot at one of Donnelly's auctions this year. I hadn't paid much attention to it until I started to clean up some of the tools in that particular lot.
It is marked Wald Mfg. Co., Sheboygan, Wis., Made in USA. Upon first glance it looks like most of the other 'cycle wrenches of that era. A little closer look and you will notice the bar on the outside of the adjusting nut. Most all of the ones I've seen have an open nut, like the Mossbergs. I have one other one where the nut is enclosed, but it is not marked.
Anyway this is my first Wisconsin wrench. Forgot to mention it is 5 in. long.
