Very interesting
Thank you @Leonov
That makes sense now. Here is a translated version

I think it’s interchangeable/replacement parts for one of their Uchida machines.

If you ever find a picture of one of the machines these work with, could you post it here?

They have so many machines they make that do just about anything and everything you’d ever need in the office, stationery, paper, industrial world.
I could be wrong in thinking it’s parts for one of their machines but it’s such a big part of the business and I don’t know of any hand held tools they made like the dotting tools of the 30s and 40s.

Speaking of Uchida, they also had at least two lead pointers made for them by the German company Dahle (in the late 1980s or early 1990s, according to Dahle).

Whatever they are they’re works of art!

The more I look at these wheels, the more I’m convinced that the design of the surrounding dotting machine ought to be quite different than the one I am used to from the traditional European manufacturers.
If the outer rim of the wheels has a rubber exterior, it is possible that it may itself the part gliding on the surface, while a pin in the main structure runs along the inner rims and uses the dents to raise or lower the ruling pen.
I dream for this contraption to have the chance to attach a pencil insert — which is almost impossible to have on traditional dotting pens — to achieve accurate traces even in the preparatory phase…

they do have a rubberized outer rim
I’m stuck in meetings, but when I get time later, I’ll send some photos to show the back and side profile

I’m still going with perforating wheels for one of their machines.
