[ARC5] What was "test unit" "I-85-D" made for the Signal Corps - US Army by Western E

[Leslie Smith]

  On this page - http://aafradio.org/docs/Command_Set_Test.html   -  you
  will see a test set I-85-A (for testing transmitters) and below it a
  unit (I-85-B) is mentioned.
  Looking at these, it is clear that the last character does NOT denote
  a minor revision, but a completely different item, with a different
  function.  To answer your "Q" - I have no answer to your question.
