This is identical to GWR N28 except that it depicts the original N23 bodywork, with doors in the central panel on each side only. When side doors were added to the panels either side of the central doors on large numbers of these wagons, they were given a new diagramme number of N28 or N29, the difference being that the latter were rebuilt from N23 happening to have the Churchward brake gear. This model is improved has the side stanchions extended slightly below floor level, hinges on the bottom of the side doors, thickened top edge strap on the side doors, thinned chassis kit location tracing on the bottom, lowered top edge of the internal bracing (to make it even easier to remove without damaging the top edge) and adjusted and unioned (Blender) rivets. Some of them now show on the illustration, but I don't know why not all of them. I'm not convinced they show on the printed model and if I do another version I will enlarge them.
