I just received a lovely gift of a gravy/sauce bowl with underplate from a friend who knows I collect BW. Serving spoon is missing, but it's still charming. It's the Mandarin pattern with dagger border very similar in design to Plate #149 in Gaston's 1983 book. However, the impress mark on the back is hard to identify. Could this be a Copeland 1870s? I've enclosed some pictures and appreciate any info fellow collectors can give me.
