[Milsurplus] Cutaway PBY

[WA5CAB at cs.com]

Well, I couldn't put my finger on all the differences either without 
reference to such manuals as I have. But when I first looked at the photos, something 
just didn't look "right".

I was assuming that the RU's were either 18's or 19's because as someone 
pointed out to me earlier this week, they each have a different junction box from 
the one supplied with GF/RU sets. It has provision for two receivers and no 
transmitter. However, I just went digging through the standalone RU manuals that 
I have. The earliest is on the RU-5, and it and the RU-11 have the same dual 
receiver junction box as the RU-19. So probably the earlier models did as 
well. So no clues there as to which model of RU is currently installed.
