Figure 62  Detail of the printed mark on the base of the chamber pot illustrated in figure 61. The associated inscription declares itself to be that of a manufacturer of ROYAL STONE CHINA from the factory of R. S. & W. The company is believed to be that of Stevenson and Williams, a short-lived Cobridge partnership of ca. 1825, but there is no known evidence that it enjoyed royal patronage. The English royal arms are charged with the cap or crown of Hanover and therefore date prior to the accession of Queen Victoria in 1837.
