Thank you for the link, I'll check out that website in a moment.
And yes, it's a variable capacitor, it had 3 wires attached to it all going to separate metal plates separated by thin ceramic sheets. I had the radio set at AM 1440 and the quality was phenomenal considering I haven't replaced anything inside, not even the speaker so it was all original; there was a little bit of static so I attempted to trim the radio and in doing so stripped the brass piece that the screw sat in and then the plastic housing for capacitor broke into pieces when taking it off the radio.
