Just posting to see if anyone has anymore info on these coaches, the one shown here is made from a grafar ex LMS coach, alot of detail taken off to show the later variant. Painted, lined and numbered, I also have an ivatt 2mt, 41277. She was shedded at Wellingborough (15a later 15B) working along the Higham ferris route. Another one of these sets went to Northampton, most of the time hauled by 41328, another ivatt tank. There is very little documentation of these two sets, I have many photos of the sets in the late 50s, using these for reference I have made 2 push pull coaches and one other coach to go with it. Only one push pull coach is shown here, if anyone has any info at all about these sets, please leave a comment below.
