Axles - AbingdonThe first axle was patented by James Starley, in 1877 for his 'Royal Salvo Tricycle'. His son, William, improved on this in 1892, and it is this differential that is used in the Abingdon axle. There should be a small brass badge on the 'housing' that states 'Starley's Patent No 7752 1892'. Later axles have the brass badge, but it just boldly states 'Abingdon'.
A number of galleries of photos of tricycles with Abingdon axles appear on the collectors site www.wooljersey.com I have put links to two below:
