[Boatanchors] Wanted: Blackhawk Engineering Passband Filter

[W8KZW]

Saw a neat construction article in an older Orr Handbook for a
glow-in-the-dark, homebrew, single conversion 80 - 10 receiver I'm thinking
of building.  It spec's a Blackhawk Engineering Company bandpass filter in
the IF.  3 Mc center frequency, 3kc passband if I recall.

Anyone have one?  Something that might work?

Thanks.
