Thanks for your input.  I thought the inductance of the winding would figure into the overall frequency but as you stated it does not.
I replaced the plastic, rewound the coil and covered it with bees wax. Its working fine and the band spread is completely correct.

Ready to replace all the caps and check the resistors to settle some of the noise down.  Thanks for your help and advice.  Your suggestion was a great way to count the windings

Thanks again
Tom
