[Milsurplus] I'd like some advice, SCR-508

[ma.locksmith at juno.com]

I've got a friend, who has a friend, with a tank.  I have no idea which
one, but he's given me the information that he thinks it takes the
SCR-508....  components:  BC-604, BC-603, ST-237.

He's restoring the tank and wants something to install for two
reasons..... visual effect AND he would like to have an intercom
capability.

He's told me that the intercom was part of the radio set.

Are these items the correct ones and are they available somewhere?  Are
the schematics available?  At what cost?
