The IZ is about as modern as 4 wheel wagons will get on "Glenburn", having been introduced towards the end of the era being modelled. Steam Era's model has plenty of detail which comes up nicely on the finished product. Era specific adds are visible in the pre-painting shot include extra handrails, buffers, a stirrup step and, as the IZ was modern in this era, it appears they were delivered with the then new buckeye coupling and so had the transition 3 link in place. As such I have replicated this with the scratchbuilt workable transition coupling by mounting a 3 link on the buckeye.
