When Flying Scot and Tornado were on the SVR in 2016, they were using the original 1930s LNER coaching stock as shown in your second picture. It was an 80th birthday treat bought by my children and our coach was a luxurious first class dining car built 1936, 80 years old.
thanks .for that i never noticed until yesterday i saw the steam pipes and though this is not a hall. 3 were made
thanks for inputThere's a tremendous mix-up here! The first two models are based on GWR Castle class locomotives and are similar. Their curved steampipes can be clearly seen. The third model has a straight steampipe, which was so in Hall, Manor, County, Grange and other GWR classes of engine.
All three carry the nameboard "Hogwarts Castle". In the first two the name "Castle" corresponds to the loco; the third model is not a Castle so it's carrying an inappropriate name.
All three have the same number: 5972 which is the number of the Hall class locomotive named Olton Hall, the engine which was used in the Harry Potter films, but renamed wrongly as a Castle. So the first and second models bear a number which doesn't correspond to the class of locomotive.
I think 1213 was its GWR number, but I am sure Alan will confirm this
