The one thing I notice on any GWR models (3D or real) is the whistle placement is always the Collett-style, with the high tone on the left side and the low tone on the right. When the 1361's were built it was the other way around, so the driver had access to the high tone first. This changed for some reason when Collett obviously introduced the whistle chain that could be operated from both sides, and a few older designs were swapped to this

Easily one of Kris’ best models
