Club Homepage Forums Classified Ads Buy & Sell - Everything But Airplanes avioncs question

So, my plane was owned by the Baltimore county police in the late 80's
they had this audio panel.
looking through my weight and balance info, found all the docs w/the avionics they installed, see pic. the audio panel is still built and retails for $4k
here's the question I promised,

Does anyone know if there's a market for my used unit?

thanks
