It sounds about right, John - although I'm not sure you can ever term 
anything in WWII as standard.  That's why I put it as "the most 
common."     I actually mentioned the 3885kHz crystal more as tongue in 
cheek, as I have a feeling none were ever made.  It doesn't seem to be a 
common aircraft frequency in charts of the time.  The O-4 on the web 
page had 2500 and 5000kHz crystals installed when I got it, but I have 
no idea if they were original...
