A friend just let me know that his rather nice 1931 Sunbeam Model 9 is now for sale. Obviously in lovely condition and fitted with a highly desirable 1929 single port engine. A great bike for someone? Send an email if you would like contact details.

Here is a scan of the relevant page for the Sunbeam models covered by the catalogue.
