ClassRoadster
Main 1923–25 Cleveland series. The structured wheelbase records the 115-inch maximum while the note preserves the earlier 112.5-inch figure. Ralph Mulford used a production Cleveland in a December 1924 Mount Wilson record and drove 1,000 miles in fourteen hours at Culver City in 1925 without engine repairs, important durability promotion but not a separate competition model.
