Lennard,
The smaller DOE to the right of the photo looks to be a German made wrench. And, I've got a number of these wrenches that came out of factory tool kits supplied with VW's, Porsches, BMW's, and Mercedes Benz's. Probably many other German auto's and motor cycles too. It is a very common German wrench pattern. Hazet and Heyco were typical OEM's of a lot of these wrenches.
