[MRCA] Another Mystery Control Box

[WA5CAB--- via MRCA]

Jeep,

It's an NT-23429, made by several different contractors.  Used in at least 
LVT-2, -3 and -4 with MAR, TCS or SCR-508/528.  The mounting points in the 
vehicles came prewired with a blanking plate over the terminal strips to 
which the control boxes were to be attached.  Use with the FM sets requires an 
additional modification kit.  See for example TM 11-2755 and 11-2756.  I used 
to have a bunch of the control boxes.  Most are now in service.
