I have 4 seven piece place settings of brass (?) and what looks like ebony or another highly polished dark wood, plus three serving pieces. The largest serving spoon has a beautiful twist between handle and bowl. There is a stamped marking on the back that says Siam and what looks like a backward S and BF in a three initial "ID". The handle of the ware is curled around a slender buddha coming out of a lotus blossom, in high relief with much detail. Any one have an idea of age and value?
