Radio dude here. . .
I just discovered this thread. I've been sick all week, including a fun visit to the ER on Wednesday (thankfully it was nothing serious, as it turns out).
CAPFlyer: Even talking about gutting out that BC-348 is like stabbing a big ol' serrated survival knife right into my heart!
I understand why it's being done, but that doesn't mean I have to like it.
BTW, your '348 has been "ham-ified". They did not run on 115 VAC. As Robbie correctly pointed out, it was commonplace after BC-348s were surplused for hams to buy them (staggeringly cheap!) and modify them to run on house power. That meant removing the 28 VDC dynamotor power converter, building and installing a homebrew AC-operated power supply, and usually rewiring the tube filament string to run on some more common voltage like 6.3 VAC (which was easy; you just put all eight filaments in parallel since they were all 6.3 Volt tubes!). Other mods were common, too, including mods to the audio output stage. As you can see with your set, hams back then had little regard for the restorers of the future, and they carelessly drilled holes in the front panels and cabinets, hacked up wiring, and so on. I have one like that which I'm in the process of fixing up (not restoring... too far gone for that!). But, I digress. . .
If you come up with a complete, correct list of the original radio gear that was used in the B-24A, please send it to me. I have a number of contacts through which I've obtained original radio items for VFM. I'll do some snooping around for you. Between Robbie and me and a few other WIXers, we can at least get you started.
One last comment. The BC-348-J is much too new for a pre-war aircraft. the -J came out in 1943, I believe. Once in a great while, I'll see one of the early models for sale, but they're rare and pricey.
73! (in "ham-speak", that means "Best Regards")
