The car with a taxation rating of 12HP was powered by a proprietary four-cylinder 1495 cc ohv engine made by Gwynnes Limited[2] and had four-speed transmission driving the rear wheels.

The chassis had quarter elliptic springs and brakes were on the rear wheels only.

Gwynnes moved production to their factory and then made about 1450 more of the original 12HP design.

In 1923 a new model was announced with the engine enlarged to 1944 cc and the name changed to Gwynne-Albert.

A plate clutch replaced the previous cone one and the suspension changed to semi-elliptic leaf springs.
