I have a set of silver flatware that was made in Warsaw Poland. It has a profile of a girl with a scarf tied in the back, a 3 on one side and a w on the other, all in an oval. I can't take a picture of the mark because it's so small, I had to get a jewelers magnifying glass to look at it.
It is the exact mark as shown under the European Marks > Foreign Hallmarks > Poland on this website.
I can't find any information out on who made it or when it was made.
