When I was growing up on our farm I remember there being parts of an old belt drive bike behind the machinery shed. The front wheel had no brake just a small hub like a heavy duty bicycle. The rear wheel had a belt rim and drum brake. Dad used the petrol tank on a pump engine, and my older brother put the wheels on a cart. An uncle used the engine for a generator set.
On discussing this with my brother he thought it was a 'Bradbury' (Bradberry, Bradbery, Bradburry?) as this was out Grandmothers maiden name. Dad buried the rest along with some other old machinery (tractor, harvester, binder, steam engine) when he had a big clean up in 1961. Has anybody heard of a 'Bradbury'? It may have been an Australian made machine from imported parts. Sadly all those who knew what happened to it have passed.
