There was definitely only one airstrip in the Buraimi area - near Jahili Fort. I first heard of Hamasa and Dau'di on PPrune. The Twin Pioneer might be at Al Khatt, which is on the western edge of the Musandan Penninsular close to Muscat border. The red day-glow paint scheme is post 1961.
I took this photo of a 152 sqn Twin Pioneer with red dayglo at Sharjah when I was there with an Argosy in 1965.
