I have a creamer that I got from my mother. It has several marks on the bottom. One is a crown with balls on the points over a shield with the letters H over W, there are 2 clubs (?) on each side. There are 4 dots on the crown. There are 5 dots on the shield, one on each side of the H,3 on the bottom of the W ( one on the left and one in middle of the bottom of the W and one on the right of the bottom of the W. The word CZECHOSOLAVAKIA is under the shield. There is a black 4 printed off to the left of the shield and the numbers 1900 are over the crown as if in the mold (no color imbeded in bottom). I can not locate anything on it. Can someone help me?
