The Galena Century Radio (GCR) Control Panel 2 x 10 Point – Base is the same unit designed for the J-Walker Loose Coupler Crystal Radio but without the Galena Century Radio marking. The Panel measures 1/2” x 6 1/2” x 8 3/8” and does not have the Galena Century Radio markings. The Panel has been milled so it can be fitted with brass as desired and can serve as a basis for a crystal radio of your own design.
