"C" model is a rare bird indeed, CBI vet to boot ! Can't speak to the radios.

I’m doing some research for a P-51C restoration and some questions have come up about the antennas and radios that I hope someone on the list can help answer. This aircraft saw service in the China-Burma-India theater in the 14th AirForce, 23rd Fighter Group, 75th squadron. 

>From WW2 pictures, the HF wire antenna is plainly visible, so I assume a SCR-274N was installed. Dennis pointed out the relay box, that appears to confirm. 

So, although I think I know what the answers could be, I defer to the experts - 

First question – at that point in the conflict, would SCR-522 be available in that theater ? 

Second question – is it possible a SCR-274N was installed in a fighter at the same time as a SCR-522 set ? 

Third question – if both radios were installed, the AN-104 antenna for the SCR-522 has a small hole at the tip – could it have done double-duty, where it was used as a supporting mast for a HF antenna wire as well as handling the VHF ? 

I’m sure I’ll have more questions as we get into this one... 

Thanks
