There are at least, in my experience so far, 5 commonly found Planet Jr. wrenches out there for us garden variety Middle Atlantic collectors (which I am). There is a small, medium, and large cutout, a medium and a large solid wrench. Pictures of these rascals are shown below with a 12" ruler (for those who appreciate metrics). Guys who started early, like the Schulz's and Marvin Wulwebber, or who published useful wrench books like Pete Rathbone's History of Old Time Farm Implement Companies and the Wrenches they issued including Buggy, Silo, Cream Separator, Windmill, and Gas Engine Companies, know of many more Planet Jr. wrenches. This fact is kind of discouraging to some of us, but then we must realize there are more wrenches out there than we can ever collect, and some of those are Planet Jrs.
