Gerhard Mitter - 1966 Hill Climb European Championship

[Nikola]

Hi Fans,
as a big fan of Gerhard Mitter and Hil Climb Champioship, let me to make a couple of question:
- since August 1965. Gerhard Mitter drove Ollon-Villars Spyder (chassis
906-010, with spyder-body)
- in 1966. G.Mitter drove also a 906-010, but with coupe-body: was this
the same car as 1965, only with differents bodies?
- is correct that on Trento-Bondone 1966. Hans Herrmann drove yet a prototype-910 (not 906)?
- on two races of end the season 1966. (Freiburg-Schauinsland and Sierre Montana Crans) Gerhard Mitter also drove 910 (not Ollon-Villars Spyder)?
- on the last race 1966. (Gaisberg) G.Mitter was again on 906-010, because he destoyed in practice his new 910?

Many. many thanks for answers and best regards,
Nikola (Belgrade, Serbia and Montenegro, ex-Yugoslavia)
