I know nothing of the circuit myself, but if I had to guess this comes from an old manufacturer's hi-fi EQ. But even if it isn't here is one way to do it:
Using the formula rocket mentioned above, figure out the frequency you want with whatever inductor and cap you have (or just build a damn gyrator and cap combo and save a hell of a lot of space, time and frustration finding the right inductor).
Now set up a transistor stage with 10k on the collector and 10k on the source, bias it to 1/2V+ and take the output from the collector. So you have an inverting transistor amplifier stage, with a gain of 1.
Now, attach one outer lug of a 100k pot directly to the collector, the other outer lug to the emitter. Now attach the inductor/cap combo you had to the wiper, and BINGO!, as you rotate the pot towards the emitter the LC network provides an easier path to ground for those frequencies in it's band and boosts them (just as a cap does when it bypasses an emitter), turn the pot towards the collector and instead of boosting, it cuts those signals as it shunts them to ground.
This circuit is mentioned in the Stompbox Cookbook, I think it was an old Tascam EQ from the 70s.
Anyway, this is one way to do it.
