That would be nice but it is definitely the mark of Michael Hafner who died by 1700. His pieces can sort of be dated on how worn out his mark is. It started as a clear jug, pitcher, ewer or whatever you want to call it but by the 1690's it had started to become foggy and worn and this mark is not super clear but not as worn as on his final pieces.
I see the maker now, definitely good to include the makers name, a lot of the fun is learning about the person who made the spoon and the life that they led and tracing the history of their silver output, thanks for the inclusion. :::
When I first got the fork I had to look at every piece by Hafner I could find online and so the assumption of the wearing hallmark was my own. The people with his pieces would attribute them later with the worn-looking marks than with the crisp ones thus my assumption. There are only so many of his pieces online however so it is not a very scientific assumption.
