That is a further difficulty! I would ideally like private owner wagons, but I haven't been able to find many photographs of Lampeter in that era, and I am not sure whether that timescale fits in with the Aberayron branch, which would provide extra traffic. Most of the photos I have seen are late 50s or early 60s, but I don't have a timetable for that period. I would need to rely heavily on readily available models, as I am not terribly practical at building stuff, so all in all, it is a bit of a puzzle!
