GWR MACAW H Bogie Bolster Diagram J30
Twenty of these 25 ton, 35 foot long bogie bolsters
were built in 1941 by the Great Western Railway to

virtually identical wagons built to diagram J25 from
1927 onwards.
The wagons continued in service with British
Railways into the 1970's and were designated
Bogie Bolster A.
Wheels are required to complete the model.
When first built 3'1" 8 spoke were fitted (Slater's No

disc wheels (Slater's No 7122). Available from
Slater's, Temple Road, Matlock Bath, Derbyshire,
