[Milsurplus] What is it: 417872 module

[hwhall at compuserve.com]

Got this from a friend & we don't know what it is.  

Marked "417872 ASSY"
Has five 6AK5/6096 tubes & one WE 5872/417A
Also looks like some tuned circuit coil adjustments and a sealed relay.
Photo attached.

Anyone know what is or what it belongs to??
