Nun and Zaiyin
The head of the nun is unbalanced, should it be fixed with hosafas dio on the bottom right part of it or shav vial taseh adif? (maybe it would make it too wide?)
The Nun in the second picture is moiel havchanos tinok?
In this third picture is the second zayin of Mezuzas moiel havchanos tinok, (Some say that 3 and a half kolmosim is a kosher nun sofit at least bidieved).
