As far as the model, another thing that people are asking about, it's a Backwoods Miniatures etched brass kit that I built many years ago when in a fit of wealth. Since then regular readers will know that I've produced the same prototype in 7mm scale a couple of times from the Mercian Models kit. In 4mm, the kit is an easier build than you might expect. All the waggly bits are etched the correct thickness so there's no tiresome laminating. Assembled with valve gear rivets and you can do a side every 20 minutes!
My loco might be famous soon - I'm sure that's Ivo Peters Bentley on the bridge!
