Boeing Brown RMI & DME Control unit by The Boeing Co.
Another very rare large gauge as found within the Boeing 757, along with the B747, 757, 767, 777.
This unit has been removed from an airline training simulator due to a power fault. The unit overall is in excellent cosmetic condition, and is sold as is. Although opportunity may exist to repair/restore the unit this is solely at your own risk.
This unit is one of the main analogue gauges/standby units which has not been completely digitised. A really lovely looking gauge, and includes its removal tag.
It offers the radio distance magnetic indication, plus the distance measuring equipment display showing distance to the runway threshold.
