Ein Sarg aus Hong Kong - Heinz Drache (1964) - Choi Hung Estate, Choi Hung

Here is the next of our previously seen clips, this time it is the one filmed outside the Choi Hung Estate. You can see how it appeared in Sumuru here, but in this film (made 3 years earlier) it also appears in the correct orientation.

One of the reasons I believe that Ein Sarg aus Hong Kong is the original source of this footage is that this same bus appears in several more scenes directly after this one as we follow its journey through Kowloon - some of those later scenes, but not all, were also included in Sumuru.
