PDM-Illston motorcycles were produced in 1914. All the engines were made by G. H. Illston of Gooch Street, Birmingham.
The range comprised three models. Two were fitted with 2¾ hp or 3hp single-cylinder engines with overhead inlet valves, and the third had a 5hp V-twin.
It is likely that the firm then diverted to war work.
