The present regulateur de parquet is a copy of the celebrated model attributed to Jean-Henri Riesener (maître 1768; d. 1806), executed in 1785 and now in the Louvre (cat. C.Dr., No. 185). In the mid-19th century, a barometer version of the clock - also in the Louvre - was made by the cabinet-maker Guillaume Grohe (for an illustration of Riesener's original clock and Grohé's barometer, see P. Verlet, Les Bronzes Dorés du XVIIIe Siècle, Paris, 1987, p. 116, no. 145 and p. 384, no. 394).
