Construction of this type began in 1929, lasting until 1933. They tended to be used on local and slow goods trains. After Nationalisation they migrated into the BR system, some lingering on into the 1970s and 1980s. Transfers for SR and BR. These finely moulded plastic wagon kits come complete with pin point axle wheels and bearings, 3 link couplings and transfers. This kit is supplied with pre-coloured moulded parts although painting can improve the appearance. Additional parts to enable the vehicle to be modelled incorporating modifications made to the prototypes during their working life are included where appropriate.
