Was PH-ABK from 1978 until 1992. Now seems to be based at Bergneustadt - Auf dem Dümpel (EDKF). Came over to conduct short joy flights with visitors of the event organised by Luftsportclub Bayer Leverkusen. The city of Leverkusen started as a factory town of Bayer and the name of the pharmaceutical company is still everywhere around the place.
