I have read very carefully all the various considerations made on the sugar bowl and I should like to add my own .
The brand "wheel" is too different from the true mark Vienna to be considered a fake. No one can be misled by a fake so gross .
I also cleaned up a bit the signs of the punching on the inside , and , as you can see from the picture there is no evidence of a previous punching deleted from the subsequent one. As I have already said everything suggests that the whole series of marks have been struck at the same time .

So I think that they are pseudos marks .
As for the dating , it is very difficult for me to make a guess.
What I can say is that I saw some examples of Hanau silver and I have one. I have observed that the repoussé work is done by hand , while the casing seems to be made on a lathe or with a mold.
In this case all the box is wrought by hammer. This of course does not mean that the piece is really old , but only that it is done the old way .
Amena
