[Milsurplus] 50s era interphone question

[Jack Antonio]

Thanks to all that replied.

The driving force behind the question is to
put together a communications suite centered
around an AN/ARC-38.

I found some info that some versions of the P2V Neptune used the
AN/AIC-4 with the AN/ART-13 and AN/ARR-15 combo,
so was curious if when the later radio was installed,
did the interphone system change as well.
