I think this is Sobraon by S. Alcock. It would help to see more of the pattern that begins on the left side of the tureen. I see a small figure on the left. To the left of it are 2 turrets nestled in tree foliage. The ladle has the strong projections off the upper part of the handle used in this pattern. The foliage looks like what Alcock used in Sobraon---some pointed, structured leaves & other wispy ones. You have a beautiful piece.
