Hey, I had one of those, 1954 I think!

Mine fed an ARC-5 rx converted for 40m [and with most of the rotor 
plates on the tuning cap pulled out to spread the band over most of the 
dial].  I had a pair of ARC-5's TX/RX each for 80, 40, and 20.

   Before that, I also used a DPDT knife switch.

Had one of those too, then "graduated" to a DPDT relay that made a very 
satisfying "clank" when actuated.  Big thing, contact arms looked sort 
of like spider legs.
