New water Tower for Hillbrow. 009 Narrow Gauge.

The only thing lacking in facilities at Hillbrow was a lack of a water tower.
This has now been rectified with a stone based ediface. Can you guess the origin of the tank?
I will put you out of your misery and tell you that it was once an 'N' gauge closed van. All of the detail was removed and strapping applied in the form of plastic microstrip.
There is a water bag on the other side which is nigh on impossible  to photograph.
