This crystal receiver has no manufacturers identification but I believe it was manufactured for resale and not a homebrew.  The circuit consists of a cylindrical coil that has 10 taps for the antenna and 10 taps for the ground and the overall construction is very professional.  I purchased this radio at an auction in Danville, Indiana in March of 2002.

Dementions:
Hight...5 inches
Width...6.5 inches
Depth...6.5 inches

    Wanted;  I would like to talk to anybody who has any information on this crystal radio or own a similar
