Another fantastic model from the line up of Replicazz from Railscale33d. This N scale Wilson B Train Grain Trailer can be purchased as a kit, where components like rims and tyres will have to be painted and glued together. Alternatively, it can be purchased assembled and painted in any paint scheme (depends on complexity)
 
This trailer would look awesome behind one of the trucks from the Replicazz series
