For The SSK, Check thread #2690. I've posted a photo of Lisboa airport taken airside in 1962 showing the first TAP Caravelle on the apron. Note the new control tower has the old tower's rotating beacon. The older photo was from a postcard from which I cropped out 'Lisboa Airport'.
TAP operated DC-6s. The Turnhouse terminal building of the 1950s does not resemble the buildings in my photos of Lisbon. I can't speak for the double-decker bus except perhaps that it does appear to be driving on the right-hand side of the road. I do know Lisbon is noted for trams.
