[Milsurplus] USMC - modded BC-312 seen online

[wf2u at ws19ops.com]

I saw a BC-312-NX about 12 years ago at Baran (Baranowsky) Surplus in  
Pennsylvania, at their storage facility which was a one-time dairy  
farm...
It was in very bad shape, some innards were missing, the dynamotor was  
there,but I was considering getting it for the uniqueness of the 24 V  
version.
I made notes on the data plates, it was a USMC unit, and the suffix was an NX.
Unfortunately, they asked $250 for the wreck, so I just left it there.
