I'm extremely disappointed to cancel my pre-order with Hattons and purchase from Hornby directly, but I don't want to risk missing out on this loco. I will be very angry with Hornby if it turns out they are playing games with Hattons by disappointing their customers, whatever the background may be.
It sounds like a really good model, and I have wanted a model of a J15 for many years. Any other loco and I would probably have risked a further long delay
