Prototype Information: The KB Mail Vans were bulk mail vans built in 1903 by Carriage Works Eveleigh to handle increased mail traffic. They featured a distinctive clerestory roof styling and matchboard side panelling, similar to the Pullman carriages built around the same time. Vans 1104 and 1105 were two such vehicles and remained in service until the early 1960s. The "Early Crimson" livery is believed to have been applied during a period when Crimson Lake Pullman carriages were in use.

This model is ideal for those modelling Australian railways, particularly the NSWGR during the early to mid-20th century.
