[K2] unlabeled (IF?) coils?

Curt
When I built my K2 several years ago, there were several tunable coils left over (?!).  The
coils used for the build had labeling and stripes per the build instructions.  BTW, the K2 works FB.

The leftovers are 10mm on each side, with grey slug, the only label anywhere is "coils" printed
twice on top.  Bottom has three pins on one side, two on the other.  There is a number "46"  stamped
into the plastic ibetween the pins.

Would anyone be able to help better identify these coils?  I have a homebrew project in need of
some transformers.

Curt,

Those are not transformers, but are shielded inductors.
I can't tell from your description, but they are either 4.7 uHy or 1 uHy
inductors.  If the tuning slug has a flat adjustment slot all the way
across the top of the slug, it is the 4.7 uHy, but if the slot is small,
it is a 1 uHy.
