Impressive! I also very much like the Deltics, so this was fun.

I'm a bit surprised that so many UK ready-to-run OO models are so inconsistent in their quality recently. It isn't only the Yanks having trouble with quality (performance, fidelity, and compatibility) with the models coming in, it turns out. I would have thought the quality control would have been more stringent in the UK marketplace. It is very slipshod here, in general.
