[Boatanchors] FS: WW2 US Navy CW Audio Filter

[James]

Radio Beam Filter Stock No. 16-R-2150.
 
Excellent WW2 Passive Audio Filter.  Great for copying through QRM.  Improves selectivity with vintage or new receivers. I've made hundreds of contacts with this filter on my antique receivers.
 
NOS in original box, tested and working in excellent condition. Needs new home. 
$40 plus shipping.
