Hi Gang ,

            Those covers are intented to keep people not directlly envolved
            in  Army ( or whatelse ) radio-network from knowing which freqs
            are used.This is to protect themselves from pain, in case they
            are captured by enemy, for what they don´t know, they can´t be
            accused for not release.In some accasions, even the radio
operators
            at radio-room don´t see the numbers in the display.Another
person
            cames by, sets the numbers, flips down the cover and leaves the
            scene.

                              Mac.

Hi Gang:

I have two of these very rare items to offer up for sale.  These are the
covers that mount on the R-390 and 390A (also the R-389 and 391)
mechanical frequency readout.  They flip up and down to conceal the
frequency to which the receiver is tuned.  There were used by the
super-secret "three latter" agencies who obviously didn't trust their own
employees from knowing these top-secret frequencies even though they
all had presumably undergone thorough security clearances before getting
into the building.  I never quite understood this.

Nonetheless, here they are.  $30.00 each plus shipping and insurance.
Sorry but I will not sell both to the same person.  In case of many offers
to
buy them I may opt  to sell them to the best offer.
