i'm new to this forum and i'm a member of a Dutch guild called St. Nicolaasgilde from Valkenswaard and i'm in the process of making a book about all our silver items.
I'm allmost finished, but there are some markings i can't seem to find.
The first is from a silver bird, a so called "Koningsvogel" (or Kingsbird) and it's probably from the early 16th century.
Total picture,

Drawing of the mark made by me.
I hope someone can help me in the next few days, because i want to take the book to the publishers??!!?!?!?!
