These are 3d models for 1:76 scale (00/EM gauge) models of LNER quint-articulated ("quint-art") carriages. Each carriage is made of three separate parts: an underframe, a shell and an interior.
Separate bogies are required; these are designed to take Hornby bogies.
These are two of the three types of carriage required to make up a full quint-art set, being the end composite and the centre third. The third type of carriage, the brake third, is under development.
