Thanks to K6YIC I have added three volumes listing military electronic test equipment - it includes brief descriptions, contractor info, manual number, etc.
=====================
Volume I lists equipment, like AN/URM-25B or TS-611/FG
See pdf page 7 for more info on contents of this volume
============================
Volume II lists components, like MX-4079/ART-41 or SG-32/TRM-1
==============================
Volume III lists equipment from before the AN/ nomenclature was adopted
