Neisse / Nysa 17th century apostle spoon

[legrandmogol]

does anybody have any old Silesian or Polish silver reference guides? I have a book on Polish town marks which dates this particular Fleur de lis mark to the 17th century but I don't have a maker's reference. The mark looks like a man's head possibly wearing a helmet. Any help would be appreciated

so it is not Neisse but munch
But in my database are 3 marks possible
Hans (Hannß) Schleich
Jakob Wilhelm
Heinrich Albertin

Can You ask the Maximilian Museum in Munch?

do you have a website for the museum? I can only find a Maximillian museum in Augsburg
