All the versions have been great sellers. Every modeller likes each one for a different reason. It could fit the period of their layout, it could have a family connection, or pure nostalgia. There are also collectors who have no intention of running them, it's an addition to there nrm exclusive/LNER/1900s etc collections. I hear so many nice stories from so many nice people on the reasons why they picked this one of that one.
I'm happy if you get the models you want, and everything works as it should and you get value for money (which I think you have, these are stunners!) let's see what comes next......................
