Thanks for your kind words, Heather. The RJH kits build well but need a measure of knowledge and experience, as you know. They were designed with the total knowledge available at the time. I updated mine in accordance with the information available but that has now been superceded. Since they were designed there's been a load more information which helps to put them right - in the few cases they are wrong - but I found it difficult to get the slight down grade over the cabs correct but after a lot of checking and filing managed to incorporate a measure of correction. Memory is a bit wobbly now but I know the roofs of the two locos were different, and I blanked off the boiler filler, on 10000 I think, and flush filled that on 10001, but I'd need to check the completed locos which are now packed ready for "the move". I also remember that the bogie frames were not "handed" so I cut and shut to correct them.
I started to take an interest in railways in 1958. I lived close to the West Coast main line and, at the time, it was an almost daily occurrence for the twins to work the Royal Scot in multiple. For sure, soon after they were demoted to the Bletchley locals and operated singly.
You are absolutely correct in saying that I have the locos coupled up wrongly - most photos show them the other way around. But I'm not entirely wrong - see:
I truly didn't pose them that way around to try to catch anyone out! I have another six photos with them the "correct" way round.
In any event, that loco you've just built is the mut's nuts.
