From Graces Guide
Carter was a motorcycle produced circa 1910, by a cycle maker who had a shop in the High Street, Grays, Essex and a garage in London Road.
He dealt mainly in bicycles but also built at least two cars constructed from either bought-in or own-manufactured parts. The same probably applied to a few motorcycles, with his own cycle frames and a bought-in engine.
