Vertical speed gauge (we think) displayed on a digital screen, however the unit has not been tested. The unit is manufactured by Thales and is in fair condition. The glass is not smashed however the screen face covering has delaminated causing the effect shown. This may be repairable, however the item is sold as seen - any restoration should be carried out by a professional.
Perhaps you need to fill a gap with a gauge, why not consider this digital unit.
