Arty, MSWJR. Thank you for your comments they are very much appreciated.
Andy. That very same thing has been on my mind from the start of this build. I even have photos that I took off the tele when I watched the film, the Titfield Thunderbolt. I'd quite enjoy modelling a bishop wearing gaiters and jodhpurs. I keep my eyes open for any figures that I could convert but, I haven't come across anything as yet. I've had no reply from 'Model Citizens' so, I can only assume that they have gone out of business.
Tim. I did apply a light walnut stain before fixing the wooden strips but, I don't thik that I'll do any more to the engine now. I know that a lot of folks get out the powders and weather their models but, I'm not one of those. I'm too frightened that everything will be ruined and so, I leave well alone.
Jon
