As with SunTour and the 8.8.8. trademark, Shimano claim a longer history for their 3.3.3. trademark than they do here for the word ‘Shimano’. As with their 3.3.3. trademark the ‘first use’ date is plain wrong - but I would expect the ‘in commerce’ date to be accurate, indicating that the word ‘Shimano’ came to the US as late as 1966.
