Ivo, I've been looking for this for ages and I think I might have a possible!
I think it's possible it could be Josephinenhutte c 1840
In my Nagel books for the J.J. Ludwig Regensburg sale there is a becher with the same foot and red rim, in latticino but instead of the strips of latticino being joined together as yours are, they have a slight clear gap between each one.
The reference is Vgl. Kat. Fischer Heilbronn (03/2005), Sammlung Dr Claus Arendt, Lot 870.
Obviously not a definite id, but you could now check it out maybe?
