Just found this topic by accident, I have been looking for 4 wheeled coaches in N gauge for a long time so I have had a go at one of these, just to see if they would work. I tried to add a clerestory roof as well, this is my try out just to see if it worked with better card and more time taken over them I am sure they will make into a very reasonable take to go behind my union mills GWR engines thanks for sharing your prints.
