Thanks Mike, Glen, Jim, Charlie, Mike, Jim, Ray, John, Bill -

The majority opinion is that the hole in the top is for a two-meter whip that 
plugged into a RCA jack near the tank circuits.  One fellow agreed however 
that he's seen a TBS-50 with a ceramic feedthrough on top, though.  

Mine doesn't have a jack inside corresponding to the hole... that, plus my 
recollection of a beehive insulator on top of at least some small rig of similar 
shape, led me to my theory about the feedthru insulator for HF at that 
location.  Perhaps there were some like that - perhaps modified by hams in that
