Selling several of my GoFlight modules, this one is the GF-166A VRP...  older black style with the (desirable, I think) double knobs, inner for the freq digits to the right of the decimal point, outer for the digits to the left...  can be set up for radio, VOR, transponder, ADF, etc. (at least with X-Plane, I have no experience with GoFlight gear and other sims...)
