The Goshawk Society is an affiliate of the Rolls-Royce Owners' Club (RROC). It is a not-for-profit organization formed to address the interests of owners and enthusiasts of the pre-war Small Horsepower series of Rolls-Royce (R-R) cars. These were built from 1922 to 1939, and are comprised of the Twenty, 20/25, 25/30, and Wraith models. "Goshawk" was the internal code name originally used by Rolls-Royce in developing the first Twenty. Ownership of a Small HP car is not required for membership in the Society, but current membership in the Rolls-Royce Owners' Club (RROC) is required.
