I don't know anything about the capacitor. If it suits the circuit, you can use it. You can probably figure out how much inductance to wind to resonate with it across the broadcast band.

The coil marked 'rotor coil' is probably adjustable, so that coupling of this
inductor with the antenna coil can be varied to control regeneration.
