I found this box at a junk dealer and thought it would be usefully.
take a look at the pic's and let me know if you know what it is and how
it was used. I was unable to find any identifying marks ( model # /
maker etc...). I would like to use it as part of a crystal radio.
Thanks for the help.

Looks like a simple "L" Network antenna tuner.

And a typical amateur radio project from that era.
Parts scrounged from somewhere else and never completed.
