Anonymous vendor, Sotheby's London, 28 February 1991, lot 151

Sotheby's do not guarantee the musical or watch movements. Both movements are currently functioning although the musical movement is somewhat tentative as it does not wind properly and needs repair. The pins closing the drum have been replaced with metal screws. There have been small restorations to the blue taille d'epargne enamels on drum and borders. Keys are lacking.

Josef, son of Josef Weichberger Senior (goldworker 1845-1881) and his wife Maria Lixl, is recorded as active between 1883 and 1899. As 'Pretiosen-Schätzmeister', he is described in 1889 with a studio specialising in gold and enamel objects of vertu. At that date he was working at 6b Kaunitzgasse, Vienna VI (MAK, Wiener Gold- und Silberschmiede, 2005).
