Old photos show Mount Kellett had a pointed top.
James Fairbairn notes here : The top of Mount Kellet was cut off in about 1959/1960 so that a beacon could be installed to guide aircraft to Kai Tak Airport with its recently built new runway stretching out towards Lyemun. I lived in the adjacent Peak Pavilions at the time and witnessed the work taking place.
(Mentioned here, the radio navigation aid was installed in 1959.)
