4 Kibri HO pylons.
Simple paintjob, nothing fancy.
They came with plastic bases, which I mounted on sheet metal to create larger grassland bases.
I then created desert/wasteland bases from styrene rod (square with a hole in) on sheet metal so they can be used for 15mm SF games (I was hoping 28mm PA also, but they're rather small for that)
