[Milsurplus] Can anyone ID these Aussie HF Intercept Receivers (used in Vietnam)

[Jim Whartenby]

Looking at the second operator from the right, there appears to be a cluster of four knobs just below the LINE meter.  That fourth knob would be the CHANNEL SELECTOR which would make the radios  R-391s.Jim

Logic: Method used to arrive at the wrong conclusion, with confidence.  Murphy

 The photo looks strange but they they are all R-390 or R-390A.  There is something mounted above them.  Maybe a TTY demodulator.  I am not sure. Tom
