Boeing RMI & DME Control unit by Sperry.

Another very rare large gauge as found within the Boeing 737, along with the B747 series. Possibly others.

This unit has been removed from a real airline cockpit. The unit overall is in fair condition primarily due to a crack in the face glasses shown , and is sold as is. Although opportunity may exist to repair/restore the unit/the glass face this is solely at your own risk. The unit has previously been overhauled but we are unable to certify its current internal condition.

This unit is one of the main analogue gauges/standby units which has not been completely digitised found on the main instrument panel. A really lovely looking gauge.

It offers radio distance magnetic indication, plus the distance measuring equipment display showing distance to the runway threshold. The cannon plug connectors can be examined on the photo and all are in very good condition.
