Finally i got them !!!!

Thanks Eddie.

The Silver case is known as the "Variation 3" case and I believe the Gold is the "variation 4". It is said that C.F.Zimmermann DKiS were only awarded in Gold cases. Therefore the DKiS doesn't match up with the Silver case.

Nevertheless, two beautiful examples of the DK which I would love to have in my collection.

Thanks for the info Andrew
