The sofas compare in profile and decoration, particularly to the arms, to the set of six armchairs supplied by John Linnell for the 3rd Duke of Argyll at Inveraray Castle, Scotland which was refurbished upon his accession in 1770 (H. Hayward and P. Kirkham, William and John Linnell, London, 1980, vol. II, p. 46, fig. 90). The 5th Duke's bank records include payments to John Linnell from 1774 and these may be the 'golden chairs' admired by a visitor in 1777. They further compare to sets of chairs attributed to Linnell at Kedleston Hall, Derbyshire at which Linnell enjoyed a long lasting patronage. One set with similarly gadrooned shaped feet is shown in situ in the Drawing Room at Kedleston (C. Hussey, English Country Houses, Mid-Georgian, London, 1956, p. 76, fig. 139). The unusual design of the legs on the present chairs appears to be unique.
