Am going to be busy with work for the next week or so but am still working on matters.

Howdy,

That looks like an RF Choke Coil and depending on the manufacturer it could be 500uH.

You did mean 500 microhenries instead of milihenries didn't you?

Here's a couple of ebay examples:

This is for a 500uH coil:

Here is a 1mH or 1000uH coil:

For those of you that are not familiar with electronics: 1 mH = 1000uH

Here's the Wiki on choke's:
