Although the Mark series machines had served Douglas well they were replaced in 1955 by a new model, originally to be called the Dart, but by the time of its release known as the Dragonfly. Although the new machine employed an engine that was clearly a development of the existing unit the majority of the mechanical components were revised. The twin carburettors of the Mark series were replaced by a single instrument housed under a cover above the crankcases with the mixture being fed to the cylinder heads by two, long curving inlet manifolds fed from a chamber cast into the clutch housing. The revised power unit was endowed with clean modern lines that complimented a totally new set of cycle parts. The torsion bar rear suspension of the previous models was replaced by a conventional pivoted fork system controlled by a pair of Girling shock absorbers. The frame was of a duplex cradle type with a single top tube and Earles type forks, again controlled by Girling units, were fitted at the front. The most striking feature of the machine was the five gallon fuel tank that extended forwards of the headstock to incorporate the headlamp mounting. Unfortunately Douglas was not in a financially secure position leading to their acquisition by Westinghouse Brake and Signal at the end of 1956 which resulted in motorcycle production ceasing in March 1957.
The example offered has been built by the vendor over the course of a number of years from parts. It is described as being good mechanical condition and excellent cosmetic condition. The wheels were built using stainless rims and spokes and stainless fasteners have been used wherever possible. The paintwork was carried out by Long Eaton Enamellers and the machine is accompanied by a Swansea V5C.
