The GWR introduced a fleet of these vans (diagram Y4) in the early 1920s. These vans could still be seen in service into the 1950s. These finely moulded plastic wagon kits come complete with pin point axle wheels and bearings. Glue and paint will be required, along with appropriate transfers. Additional parts to enable the vehicle to be modelled incorporating modifications made to the prototypes during their working life are included where appropriate
