Who won the 1911 Senior TT on an Indian motorcycle?

Oliver Godfrey won the 1911 Senior TT on an Indian motorcycle.

The 1911 Senior TT was the first Senior race held on the Mountain Course. Godfrey rode a 584cc Indian V-twin and completed five laps—about 187 miles—in 3 hours 56 minutes 10 seconds, averaging 47.63 mph.

Indian motorcycles dominated the result: Charles Franklin finished second and Arthur Moorhouse third, giving the marque the first three classified places. Godfrey’s victory was especially notable because it delivered a major international success for the American manufacturer on the newly adopted Mountain Course.

Charlie Collier actually finished ahead of Godfrey on the road in the Senior race but was disqualified for taking petrol outside the designated depot. That result can cause confusion in historical summaries. Harry Collier was classified fourth, while Godfrey became the official winner and the answer to this question.
