Many fine pieces of mid-18th century case furniture, and particularly card tables have 'H.TIBATS' stamped on their concertina-action hinges. Tibats was clearly an important source of iron fittings and was probably based in London or Birmingham (P. Thornton, 'A signed hinge', Furniture History, 1966, pp. 44-45, pl. XXIII). A George II walnut concertina-action card-table with four hinges stamped 'H. TIBATS', was sold anonymously, Christie's New York, 19 April 2001, lot 232 (£25,850).
