[Milsurplus] RP-4 Info Needed

[B. Smith]

This is my annual request for any information that anyone may have on the 
Japanese SSB TRP-4 military transceiver. Purchased in the Washington DC area 
at a hamfest.
Crystal controlled, 6  channel, SSB, CW ,6 volt, positive ground, tubes and 
those little bitty things.  Probably sold to U.S. Government agencies in 
small quantities for special missions early in the 1960's. I have been in 
touch  with the manufacturer OKI through a third party and have procured a 
brochure on the radio but  OKI  has stated that they do  not  have any other 
technical information on file. Suspicious or maybe they just got rid of all 
their old files.
