[Milsurplus] RU, GO, RAX

[Hue Miller]

There seem to be more photos about of PBY installations with RU receivers, 
or RU + ARB receivers, than
those with GO + RAX. Is this a datapoint of interest, or just a noise 
artifact?

I think it's interesting that through WW2 you had, apparently, these configs 
all existing at the same time,
and apparently, sometime into the 1950s, altho I will have to ask "someone" 
just how late he operated
the RU+GO.
