Diamond Frame Bogie, 5ft 6in wb

Like my 5'9" wb diamond frame bogies which are designed to be compatible with the former Parkwood kits requiring a filed-down Graham Farish diamond frame bogie, these have the same fitting but the wheelbase is slightly shorter, making them more suitable for my NER Quad bogie bolster of that bogie fitting. Although the 5'6" wheelbase would be better for my WD WW1&2 Rectank (and its bolster conversions) too, I think the NGS diamond frame bogies have a closer frame design and this makes them more suitable even though they are scale 5'9" wheelbase. Maybe I will get around to making a 5'6" wheeelbase bogie of that shape too.
