[MRCA] Ident of MIL crystal kit

[D. Platt]

I have come to possess a crystal kit that I can't identify.  The case is 
approx. 4" x 6" and has the typical snap clip closure arrangement.  The 
kit contains one layer of FT-243 crystals in a 4 x 10 layout of 40 
crystals.  The crystal frequencies range in /duplicate/ pairs from 4430 
kHz to 6430 kHz.  The 95% are from Bliley Crystal, the balance from 
Majestic.  I've not a clue which radio set they might have been issued 
with.  Unfortunately the tech plate was removed.  A date stamp of Nov 
13, 1944 appears on each crystal.  Anyone have a clue?
