[Collins] fs F250Z3 filter for kWS-1

[Fern Rivard]

    Cleaning up shack and have located  a brand new in factory sealed box
Collins F250Z3 mechanical filter for the KWS-1. Part #526-9080-009 which
indicates that it was the last production run with (009) so these would have
been more symmetrical than the earlier ones which were notorious for being
non-symmetrical and thus difference in between lower sideband and upper
sideband response.
Asking $350 US funds including shipping to anywhere's in north america.
