There are a number of sizes of slug, then of the wire, the screw (though
those can be changed with a soldering iron), and a number of magnetic
materials which are generally not interchangeable. In a receiver like a
51J or a 390(), there were different materials used in different
circuits. That's less of a problem in a transmitter. The KWS-1 manual
that I have, gives no hints for the slug identification. In some
vintages slugs had part numbers on the magnetic part. Without some help
that way, only stealing a slug from an KWS-1 donor transmitter will be
sure to get the right one. Though with a sample good slug and a test
coil to fit it, with a Q meter, I could match up the slug from an
assortment of slugs. I have all but that sample slug.
