The following RPM I have as "unknown".
I think I asked J. Wiles about this, but I don't remember the conversation - it was many years ago.
I have six examples of this RPM.

All the above photos were taken via a American Scope Trinocular microscope with a 14mp microscope camera.
Last three photos were take via my smartphone.
