This UMA ASI was installed in my 58P in Dec 2015 and was removed in April 2017 when the panel was changed. It's been sitting in a box at my place ever since. It has airspeed markings for a Baron 58P, so might not be of much value to anyone else unless you can get the markings changed. US$ 90 OBO. New, they cost U$580. Comes with green "serviceable tag".
