That kill switch looks ridiculous and needs taking off. An old period horn button would look the part, and do the job far better. Personally the best kill switch is the ignition key- nothing else needed!
Agree with you about the look of the kill switch but this is a Dynamo/Magneto bike, there is no ignition key. I ride a 1959 G12 Matchless it's the exact same set up. .
