The term English Type I Playing set is used to describe a range of English Playing chess sets, primarily fabricated from ivory, and made mostly, but not uniquely, in England during the 19th century. These are often incorrectly characterized as a Barleycorn-style chess set. True Barleycorn style chessmen have broad barrel-bodied Kings and Queens, and are normally fabricated from bone, rarely ivory. This poplar chess set design is characterized by narrow tapered, ringed bodied, Kings and Queens. Rooks are normally stout, full-bodied towers, often pedestal-mounted and sporting tapered staffs or flags. English Type I Playing Chess Sets first appeared at the beginning of the 19th century and were in common use through the early 20th Century. Originally, this design was produced by John Jaques, John Calvert, William and Thomas Lund, George Merrifield, Fischer, Hezekiah Dixon and Charles Hastilow, among others.
