Clerget-Blin was a French precision engineering company formed in 1913 by the engineer and inventor Pierre Clerget and industrialist Eugène Blin. The Clerget-Blin company mainly produced aircraft engines. Their successful rotary engine designs were also built in Britain by companies such as Gwynnes Limited, Ruston Proctor and Gordon Watney, to increase the output in the times of World War I.       Gwynnes Limited was a City of London England engineering business, iron founders and pump makers founded in 1849. During the First World War, Gwynnes workshops made Clerget rotary aircraft engines. The Clerget 9B was a nine-cylinder rotary aircraft engine of the World War I era manufactured in both France and Great Britain.
