Swedish Formula 3
Notes:
Most early races were held on speedway-tracks, trotter-tracks or any field
were the owner/farmer was a motorsport-fanatic.
The Effyh midget (F3 was called midget in Sweden) was built by driver
Åke Jönsson and the two brothers Folke and Yngve Hakansson (Eff-Y-H).
They did not build many cars but they sold their drawings of the car, thus
there are so many, often built-up by the drivers.
Svebe was a construction of drivers Sven Andersson and Bengt Peterson
(Sve-Be). And Bengt is/was of course Ronnies father.
