I live and learn, please excuse my total ignorance. Thanks for the information. Still doesn't float my boat, like the Ffestiniog's George England locos and a few others I can mention. Might have been useful if that information had been included in the OP's post.
My initial impressions, barring the bit about no apparent prototype, still stand. Probably why I've ended up with a clutch of Accucraft locos rather than the probably mechanically superior Roundhouses. I like something that looks more like a scale model, at least in my mind. Max
P.S. Probably not a good idea to book a holiday if you are launching an important new product, so you can manage the launch and coordinate the information that is distributed.
