This limits its usefulness for those modelling the popular 1960s steam/diesel crossover period.
These very distinctive vans, of which there were about 100, originated as three-compartment louvred vans, built on various types of underframes between 1910 and 1921.

The later contracts were on all-steel cantilever underframes.
All types used the Thow diamond-frame 5'6" wheelbase bogie. In the late 1930s an upgrading programme was instituted and plate-frame, 6'6"…
