[Boatanchors] DPDT Lever switch wanted

[Al Klase]

Lee (and John),

The WWII Navy CND-23073 "CONTROL UNIT," the audio switching box for the 
RAL/RAK receivers contains an appropriate switch.  It's a black box 
about 5 x5 x 4 inches.  I'm keeping mine for my RAL, but it's the kind 
of thing that might be kicking around in various junk boxes.
