[Milsurplus] Need Info On RT-70B/GRC

[Morrow, Michael A.]

While we are on the subject of RT-70(*)/GRC units, does anyone have a =
manual or schematic for sale of the "B" model (RT-70B/GRC) of this unit? =
 I have a 1957 manual for the RT-70 and RT-70A, but nothing for the =
RT-70B.  The only B model I've seen has a 1957 contract date on the tag, =
so it must have been one of the very last units made (1958?) in the =
AN/GRC-3 to -7 and AN/VRC-7 to -18 series of radios.

Thanks,
Mike / KK5F
