Four course range filters. I remember calling the ranges AN ranges. They
are down below 500KHz.
Two filters available, a Kenyon and a Bendix.
Selling for $20 ea, shipped to you.

They were for the old four course radio ranges that predated VORs.
There is an operational range station on a private strip in Tennessee.
Here is a link to a video that shows how it works.
