Can someone help me identify this old Microsoft mouse brand?

Suffice it to say that it is VERY old:

  • the only marking on it is the name of "Microsoft" in the upper tank, no part number or other foreign brands;
  • the internal PCB has benchmarks in Japanese;
  • the sensor is a potentiometer without end, not an optical sensor;
  • the ball is solid textured steel;
  • Yes, those are real ball bearings where we would expect Teflon pads to be now;
  • the DB9 connector is (with 7 exposed pine) and not the later PC RS232 standard female connector for devices.

At what age has this beast, and what the material was intended to host?  It seems pretty likely it isn't a PC, a Macintosh, IBM, nor even a LISA... perhaps an Apple I or II or something even more obscure?
