[Boatanchors] The URM-25D, a testament to AMERICAN QUALITY!

[ELDIM]

You Betcha!  That must have been an ole AIR FORCE unit because BEMO was the
acronym for Base Equipment Management Office from the sixties, and now all
we need is some good date codes from the components to really date this gem.
Good Work Phil. An ounce of prevention is worth more than a pound of cure in
todays' inflated world.
