a mate of mine worked for this mob from Perth several years ago, I wondered if you ever came across them.
Oversize Transport, Perth W.A.
Nullabor Roadhouse.
Slurry tank for Kirfields Perth to Telfer.
I can’t remember who took this but it looks like one from down under.
One of Hanson’s, Australia.
And just in case Spardo hasn’t seen this then I think that he might find it interesting.
