looks like an IP-500/

ours at the museum has  triple   mineral detector.
chances are  this   thing was  weird   with  the side missing etc... and he 
 just added  the  tube lash  up  which can be removed.

I would  like to  get an IP  501..  with the  audio  amp....

One with a miniature tube  added.  What could the fellow who
modified this thing been  thinking?  This unit would have been
rare even before the first  miniature tube was ever made.

As far as WWI electronics, I'll have to  be satisfied with my
1918 SCR-54-A (BC-14-A) crystal set.

I doubt  that any -A models made it to the AEF before the Armistice,
but I've read  that the earlier SCR-54 did see WWI field use with
artillery regiments for  one-way communications from spotter aircraft
that used the SCR-65 (BC-15)  miniature quenched-gap spark transmitter.
This has been claimed as the  first ever use of aircraft radio
transmission.  It almost certainly  is, at least for military aircraft.

I've often wondered if my  grandfather's unit, the 3rd Division,
18th Field Artillery, used the  SCR-54.

Maybe some day I'll get the matching SCR-65  transmitter.
