These were another set of railway buildings that I made for my nephews’ model railway as a Christmas present. They are card kits produced by Metcalf Models and are pretty good. They may not have the finesse of plastic kits, but they are quick to assemble and very enjoyable to make. The accuracy of the parts is exceptional.

Hi,
I recently came across your stunning model of the RR Merlin engine. I wonder if you ever consider selling the STL files ?
My name is Carl, I operate and run gasgasbones.com
Among other things I make models of various interesting things and my work can be seen in that website. I would dearly love to build something such as your Merlin. I have a Merlin on my website but its poorly drawn compared to your beauty !
I suspect you do not want to part with your work but its worth asking.
My email address is evans.carl12@gmail.com
Thank you for you time
Carl
