[ARC5] SCR274N in Gliders?

[arc5 at ix.netcom.com]

Found it...
Radio Receiving Set AN/CRW-3, designed to receive control signals 
from BC-375 or equiv. control transmitter.
 It was first installed in the GB-1 glide bomb.  
Some web sources say all versions of the GB-1  were
unguided, but the documentation proves this incorrect 
(and why are there movable ailerons on an "unguided" bomb?).
Manual is dated April 1945. 
If you can receive large files, Jack, I can send the manual 
but we're talking about 14 megs. 
Here's a youtube about the bomb:
