This is a standby horizon suitable for the Boeing 737. The artificial horizon is used as a backup incase of glass cockpit screen failure. This item is in very good condition and has built in level and adjustment knob at the bottom. Also the various 'flags' are present as seen in the photos. ( pulling the knob levels the horizon & secures for transport )
This item was last serviced in 2019 only 2 years ago!, but is sold as seen. No warranty is provided as to its operating condition.
The last one we had sold within 4 hours of listing! Don't delay.
