The OB wagon/gondola [this is the gondola version] started life in 1928 and is still running today. It is a South Australian wagon but has travelled to Victoria where it is also known as the E wagon and NSW as early as the 60s behind AD60 Garratts.
The decal sheet provides for many options. Price is without bogies: archbar bogies can be fitted. Alternatively, purchase BSFOBGBog with the bogies supplied.
