Well, I can tell you that "FAM" stands for Franz Anton Mehlem. that they are made some time after 1890 (that's when they introduced "Royal" & 1755 to the stamp) - and before 1920 (when the company was sold to Villeroy & Boch.
Quite a few Mehlem vases were made to order, and therefor not always easy to find comparable items to.
