A rare and compact Nav panel produced by Sigmatek. The unit is grey in colour and is in excellent condition with original seals. It features a central double concentric knob and push button on the end, in addition to a variety of other switches and buttons as seen in the photo which controls the Nav frequency of the aircraft. The unit features an analogue display. The unit is sold as is, and has not been tested to function in any way. The panel would make an ideal panel filler, within your flight simulator cockpit, or training device.
