Help needed with maker's mark on German napkin ring

[jangerd]

Is there anybody who can help me identify the maker's mark on this (Jugendstil) napkin ring? Thanks for your help!

Heichrich Haupt of Düsseldorf, listed in 1885, and the mark here registered in 1886 and still in use in 1925.

Hope this helps!
