Thanks Inge. It's a real beauty. I've seen one other like it which I think was also 3.5" gauge and may have also come from BL. Was talking with a friend the other day who used to go to the Steam Age shop in London. I restored a 3.5" gauge GNR Atlantic from about the same period. Just a tidbit of info--Patrick Stirling, designer of this loco, was the son of Robert Stirling who invented the hot air engine.
