AM & Short Wave Crystal Radio Set 1960s Vintage Radio

Description

Some kind of homebrew Crystal Set radio.
Looks like it came from a kit.
Label on the front says "3.0 MHz THRU 14 MHz" indicating short wave reception.
There are several taps on the small coil that can be connected with the blue wire with an alligator clip. The large coil slides back and forth on the coil form to change coupling between the coils.
I tested the set and got good reception on two local AM broadcast stations but not on shortwave.
Great item for the experimenter.
You figure out how to make it work for shortwave.
Very good used condition.
All items carefully packed.  No returns unless not as described.  If there is any discrepancy, contact me first and I will try to make it right.
See my other items.
Thanks.
