In 1898 Saunderson demonstrated a "Self Moving Vehicle" at a trial organised at the Royal Show which it unfortunately failed to complete because of engine failure.
The factory at Bedford continued in operation for many years making small stationary engines as well as agricultural machinery.
A fully restored, operational Saunderson Model A three-wheeled tractor from 1906 is displayed and run at the Pioneer Settlement, Swan Hill, Victoria, Australia.
Saunderson shipped tractor parts to an assembly plant in Regina, Saskatchewan beginning in 1907. http://wdm.ca/artifact_articles/saunderson.html A Saunderson Model G tractor from 1914 is preserved in the Grampian Transport Museum which is situated in Alford near Aberdeen and a 1916 model is on display at Rutland County Museum in Oakham, Rutland.
