Wolseley Aries
The Wolseley Aries III or A.R.9 was a British nine-cylinder, air-cooled radial aero engine that first ran in 1933, it was designed and built by Wolseley Motors. Intended for the military trainer aircraft market few were produced as Wolseley withdrew from the aero engine market in 1936. A larger capacity version was known as the Wolseley Scorpio. Further-enlarged versions, the Leo and Libra, were test run but did not fly.
