Talking of Alec Bennetts I bought a BSA C15 from them "several" years ago, also does anyone remember
Syd Lawton who had a motorcycle business in Millbrook Road. He was the Aermacchi dealer and a member
of Southampton & Dist Motorcycle Club. They used to have their clubhouse in Sholing.

Some bikes used a Rickman brothers frame called a "Metisse" and they built lots of frames for all makes
of engines. The fastest one I rode was a 750cc Honda 4 cylinder one.
