I found a drawing of this little industrial loco online, and for some reason I just had to build a model of it.
These engines were built to order by Hudswell Clark, so I don’t think there are two the same.
The model is to G3 and has steel frames, aluminium wheels, the body is all brass, and the buffer stocks, safety valve bonnet, and backhead are 3D printed, and R/C
