In O gauge, there are none. So here's what I'm working on. This MTH unpowered B unit was painted Baltimore & Ohio, and I bought fairly cheap. After masking off the orange areas and painting the white portion, I then masked off the white portion and painted the orange. I am using that Rustoleum Poppy Red that still looks like a perfect match (to me). I plan to add the flared spark arrestors later. The big unknown is this...will anybody manufacture decals for this paint scheme??? As with all my paint projects, stand back a ways while you look at it, and then it ain't too bad.
