While antique-fluted and hermed chair legs with 'tablet' blocks appeared in the 1763 edition of Thomas Chippendale's Gentleman and Cabnet-Maker's Director, pl. XVIII, and their serpentined crest-rails had been titled as 'French' in his first Director of 1754, the chair legs with their ball feet most closely relate to those of a late 1760's chair-pattern in the sketch-book of Messrs. William and John Linnell (see: H. Hayward & P. Kirkham, William and John Linnell, London, 1980, vol. II, fig. 76)
