"Lyonnais master potter's punches Laurent MORANT received master in 1664 , and another punch bearing the date 1711 and its origin city of Lyon. This date of 1711 is most likely the date on which he remade his punch. The 1691 control punch doesn't generally allow for dating the tins because the regulations have been misunderstood or little followed, and this vintage has been used in some centres much of the 18th century. The ewer can therefore by deduction be dated between 1711 and 1726."
My thanks to Mr JC COMMENCHAL for his expertise and valuable information !
