Information on the Wallis Bear is limited and conflicting. It appears the Bear name may have been used on a variety of Wallis tractors going back to 1902, with a claim of 40 to 80 belt horsepower. The basic three-wheel configuration is the same. One Wallis Bear survives today, from a nine or ten tractor production run that occured around 1912.
