A remnant of a bygone era - there was a time when this water pump would have worked and provided fresh water for kettles, billy cans and teapots to be heated atop a little primus stove. Sadly it's now in disrepair so you will either have to bring a thermos or traipse off to the nearest grotty little cafe - it's even further to a half decent cafe.
Ahhh, those were the days.
