Hi,
Very distinctive ``
n`` for Ludwig Neresheimer & Co: Hanau, end of 19th century (already recognized by oel). In the mark bellow it`s accompanied by Reichsmark and ``800``

(Neresheimer & Co used very wide range of marks and combinations).
I think there is French Weevil mark, too. (The image in the middle).
Oel has explained it here: scroll down to the middle.
