I for one am super excited about this news. I've been involved in TT scale (1:120) for pushing 20 years now, focussing mostly on BC/Canadian and Hungarian subjects, but I've long dreamt of dabbling in a bit of British, but the scale mismatch has put me off. I know quite a few other TT scalers who feel the same way...
TT on the Continent has a big market of collectors, too, particularly in Germany, who will buy anything they like, regardless of where it's from. I'm more of the North American RPM mindset, and look for accuracy-to-location, but yeah... these should do well enough. I know they'll be getting some of my money at least!
