Royal Copley and Royal Windsor are two names, in addition to Spaulding China, used by the Spaulding China Co., Inc., Sebring, Ohio, c.1939-1957. They produced clock cases, lamps, (sold under the Irving Miller trademark), and later went into jugs, planters, pots, vases, wallpockets. Royal Copley is the most recognized name, which was used from 1948 to 1957. The bird and rooster wallpockets and figurines are very sought after by collectors.
