I've been working on this for the past year or so, on and off. I purchased the body shells missing motor, trucks and vestibules. I could have spent a little more for a complete one, but I didn't want to mess with a runner. 🙂 I was excited to finally get it looking nicer with the addition of the aerodynamic shrouding for the trucks (made from aluminum stock from a soft drink can). The pilot (won't call it a cowcatcher) was increased in size to better match the prototype. I was really excited to take it to a friend's house for some exercise. It runs fairly nice, if not super fast for an express train. It is fairly hefty--it is made of heavy pot metal and thick stamped steel. I've been fascinated by these prewar M-10000 sets since I saw the Greenberg's collectors books in the 1980s, so I'm super happy to finally have one of my own. 🙂 I will repaint and reletter the body, but I won't go crazy superdetailing it. After all it's still a tinplate-era model with exposed screws and such.
