[R-390] OT: Which Aircraft?

On a recent visit to the Smithsonian Air and Space Museum, I ran across 
the radios in this:

Unfortunately, I didn't get a picture of the aircraft itself or the 
placard that I'm sure would have been nearby.  Does anyone recognize 
it?  I'm pretty sure those are ARC-5s and a BC-348(*).  Pretty cool to 
see them all the way they were back then.

I read where they were supposed to put one on display in the Enola Gay 
but I don't think that's this one.

Sorry for the OT but I don't really know where else to ask.  Google 
hasn't helped all that much.

Thanks,
