This shows a Caltex station, opposite to it is the Kowloon Pentecostal Church which is at 71 Waterloo Road.
Today (May 2023) there is an Esso station, next to it a Caltex one, an a bit further north a Sinopec station. To me it looks as if the 1965 Caltex station was located where today's Esso station is.
