Nice goblets, Max! The treatment of the rim ("Ranft") is that of the Bohemian ranftbecher which became popular in the early 19th century, and the style of goblet is French circa 1870. I would have thought Sèvres or Clichy or Baccarat were the most likely candidates for these, so Clichy is a good guess. In any case they are quite elaborate and must have been expensive at the time - which means, of course, that they still are.
