The rather nice turntable in the last picture is scratch built
The coach has corrugated sides added on top of the plain one supplied
The buffer beam arrangements were not as original and it had Swedish safety valves and an electric generator and lights, all of which had to be scratch built.
This was my test build, the one I take to shows.
From top left are LKM NS2 and Schoma, Feldbahn Struver, LKM NS1, Jung EL105, Armoured Simplex, CKD 30R, Lord Raglan, Woolwich, 28hp Simplex,standard gauge Simplex and finally Mars.
All use my chassis, mostly 3D printed but the RAR locos and small Simplex are etched.
