     I can just about make out the labels on the front 
panel. It does not look so much like a broadcast remote amp 
as a remote control for something like a public service 
transmitter.  If it has only an MI number and no model 
number it suggests its an accessory for something, 
especially with the high number. If your is umber gray (tan) 
it gives a very rough indication of age. RCA began to use 
umber-gray shortly after WW-2 and switched to two tone blue 
around the mid 1960s.
