I picked this up at a vintage Rally. Great story of Bernie and Lawrence Nicholson who sold british cycles on the prairies and ran a motorcycle parts mail order service for most of the twentieth century.
Bernie was also the author of Modern Motorcycle Mechanics which I had totally forgotten about but which I devoured as a young man.
MMM is apparently still available by the way.
