Well let's see what we can do. I will volunteer to be a point of collection for that requested half dozen cheap 52 footers w/o trucks or couplers. (That's 13" in ruler speak) Now just watch, not a single one shows up . You never know what winds up on those tables.
I will be set up in the engine house doorway with an assortment of new and almost new curved turnouts 46"/48", 50"/70", 80"/120", most with ROW frogs and guards.
Roo, give me a US $ amount number that translates to Aussie cheap?
