Mine arrived from Derails today. Initially, it ran indifferently , as one of the rear sandpipes was bent down, and catching on some sleepers and pointwork. A quick tweak with tweezers and all was well. Yes, the tender is very light, but has caused no problems on 18 mineral wagons and a brake van. The BR crest isn't quite as sharp as some I've seen, but won't be noticed if I weather it.
