Rosoman was convinced, as Christie's was, by certain features shared by our chairs with the Kenwood originals: identical webbing with a distinctive stripey pattern and the same blue threads typical of 18^th century tufting and consistent with the statement in the 1764 invoice that the chairs had been covered "in blue Turkey leather." Christie's was also excited to discover on our chairs a bottom layer of oil gilt beneath subsequent re-gildings, for oil gilt was widely used during the 18^th century and hardly at all thereafter. But what of the differences in construction? Rosoman says it was normal for18^th century cabinetmakers to assign different items in a suite to different craftsmen, each of whom would have had his own method of creating objects of the same external appearance.
