My husbands grandfather is from Germany and when he passed we acquired (4) salad (?) plates decorated with fruit in the middle and around the edge is fruit and nuts the rim outlined in gold. They are marked Wiuterling Rosign or maybe Rosiou(?) Bovaria Germany 54. Above that it has a "W" mark with a crown type symbol above it. I am having a heck of a time finding anything out about them, and unfortunately, we did not inquire from him while he was alive. Can anyone help?
