Spearhead in Hong Kong - Stafford Gordon (1981) - Man Kam To, Sheung Shui

The drama moves back to Man Kam To for some of episode 5: Loyalties. This time we get a closer look at the long single-storey building that can be seen in the lower image of this previous post.

As far as I can tell the building is still standing and looks to be part of the Police Post further up the hill. In the show it is a billet for the soldiers carying out the border patrols.
