That really finalises the Polly Model/John Smith platework build. Hopefully it will help, in some small way, others who are already building the kit or contemplating purchasing it. The key takeout is the confirmation that the kit fits a standard build Martin Evans Dart and somewhat transforms it.
Good luck with your builds and feel free to share here photos of your achievements.

An update ]You may recall the problems I had a year ago with painting the loco. Many attempts and repeated problems with “blushing” of the paint. Since then, I have already repainted the boiler once as it wasn’t doing to well when sparks from the chimney hit it plus the boiler bands had melted their way into the paint. It happened again and the boiler needed another repaint. This time I decided to do something different and asked the company again that had said, back then, they couldn’t match the paint to Bob’s sample. This paint was in another league compared to the last time no dramas and right first time. The match is pretty much the same as the previous paint albeit a gloss rather than flat. It is a Valspar product apparently out of Holland so I assume would be available in the UK. The product ID is on the cans. In New Zealand I got mine from Linkup Paints The boiler barrel, throat plate and firebox wrappers are the new Valspar product, everything else is in the original Dulon product, which I don't think I'd recommend now. The barrel and tanks don't seem to match in the photo but if you compare the firebox with the cab that is what match is more like in the flesh. I guess something to do with camera and lighting It remains to be seen what happens after I've run the loco. Pete

Hi Pete.
I don't know what that paint is you have, but to get the best out of the coating on a working steam loco, the ideal paint is a "vehicle enamel". It should then be able to stand the higher temperatures, and cure extremely hard and flexible, but not brittle. Bob.

Hi Pete. I don't know what that paint is you have, but to get the best out of the coating on a working steam loco, the ideal paint is a "vehicle enamel".

How would you know what the product is? They seem to give their products proprietry names and even the TDS deoesn't extactly say what it is. This product is for vehicles but whether or not its is an enamel is anyone's guess. I have used epoxy enamel in the past and that is just about bullet proof, but they have a very restricted colour range with them. Pete

Hi Pete.
No problem. As far as the enamel goes, any paint that is designed for vehicles, should be fine on a steam loco. All vehicle paints maust be resistant to solvents, dry extremely hard but remain flexible without cracking, and also withstand high temperatures. The surface coating on a car can quite easily reach 120C on a hot sunny day, even in UK. It is not unknown for people to get quite a severe burn from coming in contact with a car body, depending on colour. The darker it is the hotter it can get, and so must be able to withstand the high temperatures
Bob.
