In addition to the MTH plastic R50b, the prototype has been modelled by 4 different brass importers in O scale 2 rail.
- Max Gray
- Custom Brass
- Precision Scale
- Sunset
2 railers looking for an R50b have quite a choice (including converting the MTH). The Max and CB models came in unpainted. The PSC model was offered in painted and unpainted versions, while the Sunset model was factory painted. Lettering on R50b's could either be gold or dulux. Prior to 1952 PRR passenger equipment lettering standard color was gold. During that year the PRR revised the lettering standard for passenger equipment (including locomotives) to use "dulux" - a mustard colored paint.
