Re: Anybody seen such a trig before?

I've seen one of these, on the west coast of Tasmania.
It is a fire lookout tower and is from quite some time ago.
Surveyors used them as they could be sighted just like a normal trig beacon, and because they are concreted into the ground, they don't move - like communication towers, water towers, and the like.
See TP7112.
