The same mark was used by Gebruder Dingeldein;``Augsburg`` acorn being very popular.
I have a goblet with Nurenberg N and later saw exactly the same piece with Augsburg fantasy marks.
Gebruder Dingeldein moved to America and continued the production.
What is the object discussed here ? Do not get disappointed; after so many years I gave up believing in great finds like 18th century Nuremberg in flea markets or sold by ignorant dealers.
