Blackstone & Co

Blackstone & Co. was a farm implement maker. In 1896 they built lamp start oil engines. By 1912 they had developed a new diesel engine that ran on vaporizing oil and was fired by a spark. It did not need a hot bulb like most engines of the time.By 1919 they had mounted a 25 hp 3 cylinder version in a crawler tractor, which they built till 1925.

By 1929 they were building diesel engines for the Agricultural & General Engineers (AGE) group. Richard Garrett & Sons assembled some of these tractors. They were similar to an International 15/30.

AGE collapsed in the early 1930's, but Blackstone & Co. continued as an engine builder and was taken over by R A Lister and Company in 1937.
