Victorinox Confoederatio Helvetica Classic SD, Ambassador and Huntsman

A nice trio of commemorative Swiss Army knives with Confoederatio Helvetica 1291-1991 inlays. A Classic SD, an Ambassador and a Huntsman.

I already had a Huntsman like it (except this one is mint), and I had seen pictures of the Classic SD as well. But the middle one is uncommon if I am correct. It’s the only 74mm Confoederatio Helvetica model I have ever seen.
