Haviland Teapot, sugar and creamer with demitasse cups and saucers

On the bottom of these items is a marking H&C with a small circle and dot beside it. Underneath a line is "L". The tea pot is about 10 to 12 inches tall and the sugar and creamer are smaller. The cups are demitasse cups. I received this from my mother-in-law and was told that this was my husband's grandmother's wedding china. I believe that this is Limode China.
