His UF-1 is probably not a "standard" U.S. Navy model - the UFs were 
rather huge RTTY terminals used late in the war, basically consisting of 
rows of Western Electric racks stuffed with goodies.

His radio is a real oddball, for sure. That is also a very weird 
frequency band. At least in the U.S. military, it spans several slots 
assigned for other things (TBS, Marker Beacon, and Remote Control).

Any other useful markings on this?
