The "N" was later removed (see here). Ex LN-KLV Nor-Fly. Purchased by a private individual early August 1976 and displayed on the spectators roof terrace. So it couldn't have long been there when I took this shot. When that spectators terrace closed down the aircraft was moved to the Visitors Park at Munich Airport and was painted as HB-IRN. Still there as of 2019. I took a photo of this aircraft still in active service as LN-KLV in July 1975 (see here).
