This is a classic Boeing CDU unit, which was the precursor to the modern FMC/CDU units on the New Generation 737. These units controlled a variety of aspects of the flight and were found in both the pedestal and overhead panels of the classic Boeing series prior to the 737NG.
This unit produced by Carousel, was overhauled in 2002 in the USA. The unit does not have any damage, other than signs of use in commercial flight. The panel has also been in storage and would benefit from cleaning. All the buttons and rotaries work as they should including the dual rotary selector, however note that the panel has not been tested and is therefore sold as seen. Any attempts to restore to working condition are at your own risk. The panel would be an ideal gap filler, or display piece. The two rear cannon plugs are in good condition.
