It's  probably not too bad as a crystal radio. The same basic circuit is 
used in  Heath's CR-1 crystal radio,
I mean, a series tuned primary circuit,  transformer coupled to a parallel 
tuned circuit to the diode.
The Heath  circuit works quite well. This circuit works well with 
electrically short  antennas.  
The 123B has one of the longest instruction manuals around  - oops, I meant 
"shortest instruction manuals".
It's one page.

I imagine around  port towns they are more of them than  in the desert of 
Arizona!
This is the only  one I had a chance   to get?  Had it  for years...
Trying to use it must have  indeed  been a challenge. Initially  I  grabbed 
it as it was  another  crystal set to go with my earlier ones. Never  did   
try it. Now  I may have to  just  to see how horrible the setup  is.   
Years  back i did  play  with the IP-500   with a triple   detector.

I DO NEED A BUZZER COVER   FOR   OUR  IP-500!  Help?
