Dear 'sichel', thank you very much for the point! I don't want bother you anyway, but shouldn't be the correct type of this Saurer: Saurer 1 CR1D or Saurer 1C CR1D? As CR1D is only the designation of the engine-type, not the model designation, in my mind. May be I am wrong, but think so, due to some informations in the Kopacs-books, that my assumption could be right
