Both books, Weltliches Silber and Weltliches Silber II are still available from the Landesmuseum Bookstore. All of us have limited budget, so I recommend to go for Weltliches Silber II. This one is focussing on Swiss Silver from 1700 onwards up to the 20. century. But it has still a lot of earlier silver. Part II is also nicely organized with all marks in the back as a register and also with each iteam in the catalog. The maker of your Morges spoon is also listed. And it has an extensive flatware section.
