Viennese or Czech, 1800s or early 1900s dinnerware set

I inherited this dinnerware set from my grandparents. It comes with 32 (!!!) dinner plates, a wide variety of serving bowls, soup tureen, etc., but oddly only 9 salad plates. (I'm guessing a number were broken or lost.) I think these were a wedding gift for their wedding in 1926, but we seem to recall stories that these were passed down from a previous generation. My grandparents grew up and were married in Vienna but ancestry is in Moravia (now part of the Czech Republic.) The items appear to be handpainted, because there are slight variations. There are no markings and we know nothing further. We would love to find out more about when and where these come from and whether they have any potential value. Shown here is a serving dish that is 12" in diameter. The dinner plates look identical (but are shallower) and are 9.5" in diameter.

Good
