[ARC5] The BC-221 low frequency tank circuit puzzle.

This was common practice at least in the military TM's, TB's, T.O.'s, etc.  
up until about 1944.  M - x 1,000 and MEG = x 1,000,000.  At least in the 
military manuals, there was usuall a note that said this somewhere on the 
schematic.  After the change, the note changed, too.
