This was a corporate aircraft operating for Heitkamp Bau Holding. Photo taken by my father during his business travels. I decided not to crop it so as to appreciate the other types in the photo. Two Swissair Convair 990 Coronados, an CSA Tupolev Tu-104 (they also operated the 124 but I think this one is a 104) and an Olympic Airways Comet 4B.
