[MRCA] BC-224 vs BC-348

[Herb Mooney]

 Ray, you are my kind of mentor, but a bad bad man so my wallet tells me
LOL. :-) Yes,so I'd love to find someone with a working restored BC-348
with Dynamotor to trade for the BC-224 & Dynamotor I have. I have a few
BC-348s that have been converted to12 volts, not tested yet, and an extra
dynamotor, so I planned to learn how to restore one of the BC-348s black to
original condition and power option with the dynamotor. If I can make a
trade even better. NOW you open the can of worms and tell me about an APU I
need to get. I'm all in, but how hard is that to find...in Florida and will
it fit in my StapVan Bomber? I'm planning a hefty overhead console for the
ART-13; BC-348, 3 ARC-5 receivers and an LS-3 speaker so far. I will need
to find a home for the APU I guess. Here's a picture of my land based B-29
(actually a Grumman P-30 Step Van RV conversion) about to be polished up
and vinyl wrapped like a WWII aircraft...
