In 1786 the most active members of the Lugo workshop appear to have been Francesco and Giuseppe, the sons of Cassiano Zanotti II. A lock dated 1789 and almost identical to the present lock is fitted to a gun in the Musée de l'Armée, Paris (inv. no. 06187), illustrated in Nolfo di Carpegna, 'Notes on Central Italian Firearms of the Eighteenth Century', part II, J.A.A.S., vol.
