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).

It later spent some time on static display on the Frankfurt am Main airport spectators terrace. When that closed down it moved to the Visitors Park park at Munich Airport and was painted as HB-IRN. Still there as of 2019.
