The previous post (part 1) was re-written and the years corrected after a reader who used to live in Wharf Road emailed his observations of the picture. Please read the updated Part 1 again. Below is another picture from the same period from a different angle.
Note that the 1950s police station at the end of Block 4 was not built yet. Instead you can find swaying coconut palms. At the far left, part of the original wharf building was shown.
The black car was an Austin 10 made by the Austin Motor Company. In the 1950s, several Wongs owned a few of these and used them as taxis. For the technical folks, the 1125-cc four-cylinder side-valve engine produced 21 bhp (16 kW) and drove the rear wheels through a four-speed gearbox.
For the layman, it means that it could get you from point A (say Wharf Road) to point B (say St. Anthony's School) faster than a bicycle.
