The problem is obvious, where to start. It could be any of a number of different countries. There are two things you could look for to help us out.
The first is an engraved monogram, anything there? The styles of engraving vary from region to region. I don't see any in your picture, but would like to make sure.
The second thing to look for is scratch engraving on the bottom. First get a good loupe, move the bottom of the plate around in the light. Look all over the surface. Most pieces have some kind of scratch engraving. I have pieces which have the original weight and even the original cost on them. Most museum catalogues ignore these, but they can often tell a lot.
There is one more clue,but probably impossible to obtain. Silver quality. On the outside chance a lab or smelt is in your area, that can test the silver quality. Acid testing, or touchstone testing is better than nothing but x-ray florescence is best, although your piece might be too big to fit into most machines.
