Western Maryland #190 Lionel O Scale RS-3 Diesel Engine with Horn, Direction

Uncommon O scale Lionel RS-3 diesel in Western Maryland livery. Has horn and direction switches. The two number plates at the front sides have worn off. This unit was used on a track table with hall switches, hence the magnets that were previously applied to the underside. I can find pictures of WM unit 190 in real life, but haven't found any examples of a Lionel WM RS-3 #190.
