It might have been the Astolat show a couple of years ago, maybe not, but I discovered a 'train pack' from Ibertren containing this and three crude wagons for £25. This when the Ibertren Cuckoo chassis were off the market and changing hands for silly money. Unusually for me I'd mislaid it and it turned up in a small box marked 'possible 09'.
This is the 009 modellers equivalent of the pot of gold. Now with the slightly longer, but otherwise similar Fleischmann 040 I have the basis for two more locos for Garn.
