[Milsurplus] WW2 B-29 VHF radio?

[Kargokult@aol.com]

I am reading a super interesting book, "Flight of the Lucky Lady",
fiction,  based on all real life accounts from another plane, the  
"Mark of Zorro". Crew is using a switchbox with these channels 
mentioned: B channel - intraflight comm.  C  channel - air/sea 
rescue comm.  D channel - fighter comms. Also a setting for 
plane intercom only. 
What control box and radio would this be, on a B-29, 1945 ?

Also- no mention whatsoever of CRC-7. When the crew bailed out,
they had one-person dingys, thus no "Gibson Girl". The "Gibson
Girl" radio was DROPPED TO THEM, along with a 5-man raft, from
a "Rescue Dumbo" B-29 plane. Still, no mention of handheld rescue
radio. The SAR planes, BTW, sent homing signals for picket boats 
to find their way to the downed fliers. (Still any controversy over
why aircraft transmitters had LF/MF range? ) Also, mentions B-29 
sending homing signals  for fighter planes to follow it home, sez 
fighters could follow signal on "dial" of (i assume) ADF.  ( But what 
set in Navy fighter plane of this time?) 
Book published 1954, sez based on real events, "and often closely
based" on experiences of crew of 'Mark of Zorro'. I assume author
was flier, or very closely associated with aircrews in the war zone,
because of author's depth of detailed knowledge of flight procedures
and details of Pacific bases.
Book was author autographed!  I always like to look for the plain
cloth cover books, the ones with the old,  straightforward plain 
cover format and tyepface, as compared to later glitzy glossy
prints. I always find a gem.
Your comments?
