Wonder what it's from? Hefty wire.. lots of neat windings, needs some TLC but would look nice in something.

Just curious what the markings are on the left end of the unit??  Might help ID it [maybe].

She's pertty..........but all of those windings do not guarantee that they are in a ham band.

Sorry for the lapse. The choke disappeared. Fat Mama Kitty found it behind a console and made a racket playing with it banging it against the wall!

The markings on the end is a number "9308". That is the only number on it. I think tomorrow it will visit the MFJ antenna analyzer and see what resonances may appear.

Most Millen stuff I've seen has 5 digit numbers, JW Miller used 4 digit numbers though, might be one of theirs.

I knew it was one or the other.  I have their catalogs, when I get a chance I'll check out the number.
