More info on the handsets I seek

[J. Forster]

Thanks to another lister, I have some more information:

What I seek is  purportedly a "standard military handset" with a 6 pin conn. The
pinout is as follows:

A.......GND
B.......Rx Audio
C.......PTT
D.......TX Audio
E........+10 to 30 VDC (VIN)
F........Signal Gnd

Other possible numbers are H-189/GR and H-250/U

Thanks again,
John
