Was that answer from Anschutz GmbH in Ulm, or from someone here in the US? If it was someone here, they may not have records about anything that was imported before they secured the distribution rights. If that was the answer from Germany, I am very dissapointed....
Have you tried contacting Savage? Since they were the importer of record at the time your rifle was manufactured, their records may be better (considering also the age and status of Savage).
What information are you looking for, anyway? You may be better served by researching some vintage gun mags for reviews, or maybe old Gun Digests or Shooters Bibles.
Co-incidentally, I have close to hand a 1967 Gun Digest and cannot find any mention of this firearm (but there is a favourable review of the new Smith & Wesson stainless steel Mdl 60 revolver...if it proves popular, they may offer other guns in stainless...).
Good luck,
MM
