David in the UK sent this photo: "Found this in a family album, looking at old photos, I come to the conclusion it might be a Norton. The photo is at least 100 years old as the person riding it unfortunately died in 1912"
Five persons have informed us that this is not a Norton. Mike suggests a 1910 single speed Humber. Reece agrees to a 1910-1911 Humber. Alf thinks it must be a 1909-1910 Humber. Martin has checked the registration and the number dates from 1909. Howard thinks it must be a 1911 Humber. So a c1909/1910 Humber seems the best bet!
