This item is a very rare gauge from the main instrument panel of the classic B737,727. It would also suit the B707, 747, aircraft and other non-boeing classic commercial aircraft.
The unit is in pristine condition, with very little signs of heavy use. This 24 hour clock was used to monitor the time elapsed on the flight etc and even today the cockpit has one in front of both the pilot and first officer on the modern airliners (although digital units not analogue)
The unit is produced by Aerosonic Corporation and overhauled previously by Wright Instruments Limited, and American Avionics Inc.
Extremely rare to find. Almost impossible in the UK. Available to ship worldwide. For the serious simulator builder, or replica cockpit restoration project, or simply a display piece for your home or office.
