Sorry if this is a bit off topic, but can someone give me the contact information for Steve Hamel in the Minneapolis area? This is (very loosely) related to pre-War Vincents in that someone suggested that he might have a sprocket for the Burman on my 1928 Ariel even though the Burmans for Vincent came later when the output shaft had a different spline. For that matter, contact information for anyone else who might have a new or used sprocket for a 1928 'Q' Burman would be greatly appreciated. The sprocket teeth can be totally worn because I only need its splines as a donor for attaching a larger sprocket to lower the speed of the engine.
