These chairs bear striking resemblance to a pair of chairs (part of a set of four) supplied by Gillows for the two libraries at Hackwood Park, Hampshire and sold Christie's, London, 20 - 22 April 1998, lot 55 (£84,000). It was common that standard designs were altered slightly so that they were bespoke to each client or room they were designed for thus explaining the difference to the shape of the back and to the carved arm supports.
The journeyman stamp J.B. is for John Barrow, son of William Barrow, who was apprenticed to Leonard Redmayne on 26 September 1826. The stamp J.B. is found on other known Gillows pieces in the 1830s, including a pair of George IV yew-wood and elm shepherd's crook armchairs, formerly owned by Perceval Griffiths, and sold from The Collection of Benjamin F. Edwards III, Christie's, New York, 26 January 2010, lot 230. Susan Stuart records an oak library table of 1841 and a brown oak social table of 1848 by Barrow (See S. Stuart, Gillows of Lancaster and London 1730-1840, Woodbridge, 2008, p. 215).
