Douglas 1923 4 HP 596 cc combination

Quote from: the website
In 1915 a 596 cc model was introduced to cater for  the need for a more powerful sidecar puller. A notable difference in engine design with the  2   HP model is the wet sump oiling system.  A year later the 4 HP model was improved in a number of ways. To mention a few: other front forks, new design of exhaust, frame  and tank alterations, front and rear brake changes, many  small engine design improvements.
