Congrats. A beautiful locomotive. I have seen it at the Gauge 1 Sinsheim meet last year. It was presented as the model made to celebrate 70 years of Fulgurex. You might know that Fulgurex has announced a set of matching carriages http://fulgurex.ch/modelle/1/gb-wagen/gb-wagen.html?
By the way, I myself would never use the smoke of such a locomotive for fear of spoiling the finish.
