No specific locations here but some nice aerial views taken from the opening section of Episode 6: Fan Tan Man. The quality isn't great (remember, these are screen grabs from a DVD that was made from a VHS copy that was done when the original series was shown in the UK back in 1990/91 (can't remember when it was exactly - I just wish ITV would release a proper restored DVD...)
The first two pictures give us a nice view across the Central harbourfront. The little bit of harbour water seen on the lower right on the bottom picture has now all been reclaimed and those piers you can see have completely gone.
The above picture shows the area around the (now named) Lippo Centre. We can see Hong Kong Park being created from the old Victoria Barracks and the tall building on the left is the Queensway Govt Offices. Just to the left of that is the shell of what was to become the Island Shangri-La (2 Pacific Place). Eagle-eyed readers may also spot the Hongkong Hilton just behind the B.O.C tower.
Again, another shot that is now be water-less courtesy of the reclamation that the IFC sits on top of. Of course we can see the old (and better located) Star Ferry piers and to the right of there is the last incarnation of Blake Pier. Actually, until I saw this I wasn't too sure where it was but now I can see it started right next to the GPO in front of Jardine House. I guess Man Yiu Street occupies some of that now.
The last few shots show the old helicopter landing pad that used to sit on the waterfront in front of Caine House (that's the low-rise building we can see at various distances on all three snaps, but is at the background on the lower picture) - it's better known as being the Central Police HQ. The are where the landing was is now partly occupied by the intersection of Lung Wui and Lung Wo roads. The site is largely empty still but slowly being redeveloped (into what?). The basin on the right in the top picture was originally part of HMS Tamar and now has the new Central Govt Offices on it.
