Bettered only by Ove Fundin......10 years and finished no lower than 3rd. And that was in the era of 1) a single meeting world final...no room for error, not even an engine failure 2) strong opponents ie Briggs, Moore, Craven, Knutson, Plechanov, Crutcher. Could possibly have been 12 years running if the Swedish speedway authorities hadn't banned him in 1966, as he came back in 1967 and won his 5th title.
