Hi All - can anyone help to identify this small cup. It is on a spreading circular foot and has a bulbous body. The wide rim has six sides. Cast scroll handle. Chased floral and foliate decoration. It is hallmarked to the base twice with a scroll S with 3 dots on either side, and twice with a building or structure such as a bridge? I believe these cups were typical of Russia or the Baltic areas. Any help would be much appreciated. Thanks Joho.
