[Milsurplus] 400 cycle 3 phase and WW2

[Bruce MacMillan]

I got to poke around and take some photos in an ex FAA DC-6 last summer. 
It was wired for sound. It had a couple of 3PH 400 cycle motor gennys in 
the back, a 115vac 60 cycle inverter system & buss, a 115vac 400 cycle 
buss as well as 24vdc & 50vdc buss. There was also a 115vac 400 HZ UPS. 
Lots of Collins nav equipment and a test/work bench in the middle of the 
plane. Don't know what happened to it as it was slated for aluminum foil 
production but they might have found a buyer. I did get the Collins 
618T3 and 180L3 out of it though.
