USRA Heavy Mikado. Nice model. Perfect size steam loco for a small to medium size 1918 - 1955 era layout. Looks like the mid to late 70's version. With a fresh traction tire, these can pull 15+ 40 foot freight cars on level track no problem. Its the "better" Rivarossi 3-pole "can" motor you have there and not the earlier ball bearing open frame version. The ball bearing version is not often successfully revived. Usually the can version only suffers from rust on the steel parts and corrosion on the copper and bronze brush and armature contact surfaces. Sometimes the windings get shorted or the wire breaks from the armature poles; pretty much ending the motor's working life. They have that weird bronze wire mesh brush on one pole. If the armature and windings are good, a cleaning and light lube are usually all that needs to be addressed to get them running again. Sometimes the bronze wire brush springs get weak, but can often be bent slightly to exert more pressure. Over-do the springs and the brushes wear out fast, though. I don't think replacement brushes are available anymore, either. Run it regularly - say 5 minutes or more per week, and it should prove to be reliable and mostly trouble free. Leave it on a shelf too long and the motor will probably freeze up again.....
