As Thomas noted in his reasons for the ID, two of the buildings seen in the screen capture below are still around today.As you can see by the Streetview below, the road now sits underneath the Wanchai walkway which joins Wanchai MTR station with Immigration Tower on (what was) the harbourfront. It's a familiar walk to anyone who has had to apply for a visa or permanent residency in HK (I myself had to do multiple trips courtesy of various visas for myself and children followed by our ROA applications).
Anyway, the buildings Thomas noted as still standing are the two on the left hand side of both pictures. They've changed a bit but you can still make out the same aspect and dimensions as they were back in 1974. The closer one is the Hong Kong Building and was built in 1966, the one next to it further away is Mercantile House built a year later.
Once again many thanks to Thomas Ngan for the ID.
