This saucer is nicely printed in a bright blue, no chips, with slightest normal wear from use and an ever-so-faint hairline in the well an inch and a half long. It is larger than normal, almost 5 7/8 inches across. The disguised numerals mark was used at Worcester in the period from about 1775 through the 1780s. Ref T1016A.
