These came from the builder of the 7 1/4 inch gauge 15x and part-built Black 5 I had in recently. Parts for a pair of heavy duty 7 1/4 bogies, comprising turned steel wheels on axles, welded up chassis, pivot plates and a large box of springs, bearings etc. The last three pictures show a set made up and mounted on a passenger trolley - this is not for sale (I need it for the railway here!) but gives an indication of size.
Bogie chassis 17 inches long
Wheels 4 1/2 inch over tread
gauge | 7 1/4 inch |
