New Surplus Ametek Aerospace Turbine Speed Indicator pn 128-384028-3 w/ 8130-3. These came in an inventory we purchased recently. Indicator is packaged carefully with foam all the way around it to protect the instrument. Indicator does come with an 8130 from Raytheon Aircraft Company. We believe that this indicator is used on the Hawker 400 and 400XP Aircraft.
