haviland limoges tea set

Hi everyone! I was given this and is been sitting on a shelf for awhile now. So thought id see what i can find out about it. I have a tea pot, creamer,and sugar dish in gold abs ivy. Then I have a sugar dish in a rope pattern. I think the ivy set is older. Being they didn't stamp their logo on it. But wrote it in the glaze. The rope style has the logo stamp. Very nice solid heavy set really. Anyone know of where i could look up age possibly? Thanks for looking!
