"What? Not that old dinosaur again? I thought it was gone for good."
No. It's still around. The old dinosaur is making one more foray onto the exhibition circuit in the USA, and what a foray it will be.
It's going to be on display at the 38th National Narrow Gauge Convention in Minneapolis September 5th - 8th.https://nngc-2018.com
If you've forgotten what the layout looks like, then the nice people at the show have put up a page for it.https://nngc-2018.com/modular-purespring/
