HO Scale Sunset Models Prestige Series Pennyslvania 0-6-0 B6Sb

Brand new in the box HO Scale Sunset Models Prestige Series Pennyslvania 0-6-0 B6Sb.

During 1916–1920, 238 of class B6sb were built. These were the final, definitive type, and had a Belpaire firebox, but were otherwise little changed from the B6sa. The final 97 locomotives had piston valves mounted outboard of the cylinders, instead of inbound as previously built, giving the cylinder assemblies an outward cant at the top, rather than inward.
