I have a Marx 333 engine that was given to me as part of a box of other train stuff, the real prize being a ATSF Mimbreno china tea pot. I have had it set aside for years, and just got around to testing it, the motor runs!
It is missing rods, pickups etc. I know many of the parts are available, but are there parts diagrams to show what is needed, like there are for Lionel?
