Vintage Crystal Radio Homebrew, needs coils

This is in interesting homebrew that I got in it's current condition, looks like it just needs coils to work. Appears to have some sockets on a plastic plate attached to the back of the variable tuning capacitor where the coils should go. It has a nice fromt panel with knobs, Fahenstock clips and a headphone jack, and attached to the back are a double gang main tuning variable capacitor, a trimmer variable capacitor, and a vintage Sylvania ceramic body 1N34 diode. Im selling this for $19, which is less than the sum of the parts would be worth, Should be an easy project that is mostly done already.
