Just finished an upgrade to Garmin 530WASS in my Twinkie. Don’t know if you’re heart is set on the KNX stuff but thought you may be interested in the following: - NARCO MK 12D TSO, SN 53936 W/ mounting Tray (rebuilt in 2011) and the corresponding Narco Indicator ID 825 W/glide slope SN 16956. Both units were working when removed. I also have a Narco ADF 841 TSO, SN 03365 ADF W/Mount Tray, the corresponding Indicator (ID 841) SN 10705 and the NARCO NA 841 Antenna, SN 1726. Green serviceable tags with the units.
These units will go cheep to an ICS member because I did not want the local avionics shop to cheat me out of them.
