Hi ,
Honeycomb, dimpled or Diamond ??,( Zoude made them all) its difficult to tell from the photos ,hammered is a term best left for silver objects ,you cant hammer onto glass,D I still think is not from Namur but possibly French and possibly the earliest one maybe towards the beginning of the 18th or even the late 17th c , photos can only tell you so much ,in the hand is the only way to be a little more certain , books are good and yes i have lots(though not enough) but books can be very wrong,viewing and handling over many many years is the best way to learn then you will find the more you learn the more there is to learn, its good fun though along the way.
cheers ,
Peter.
