I was wondering about the name “2MR1” which seemed to be known by myself. So I searched my own picture collection for this. The result was I should blame people which decades ago produced name confusion (knowing it does not help).

What I already have are pictures like shown here: https://www.armedconflicts.com/Mitsubishi-2MR1-Type-10-1-C1M1-19968-12295-24335-33328-19978-20390-23519-26426-C1M1-t8631
The one above I shall store as “Mitsubishi Tobi”. Thanks for your interest.
