This gentleman is astride a Baker with Villiers motor. It looks like the engine is a Villiers 172 Super Sports. Bakers had a reputation as being good quality lightweight machines.
Frank Baker who set up the marque had a long history in the motorcycle industry having formed Precision Motorcycles in the veteran years firstly supplying engines and then complete machines. After the First World War Precision merged with Beardmore, and later the quirky Beardmore Precision machines followed. Baker was formed as a marque in 1927 and sold out to James in 1930.
|Late twenties Baker motorcycle, maybe a Super Sports model.|
