This is Wedgwood Edme. This was our everyday pattern for about 25 years. I loved it and we still use it in the guest house at our farm. (My sister had this pattern also.) The serviing pieces are especially graceful.
1 Back side of a new one-piece molded mounting, left. Little space between settings; settings appear to be joined by a flowing channel of metal. The back of a typical vintage mounting, right, assembled from many separate pieces.
