Capo Di Monte ewer with cherubs in Garden of Eden

This ewer was found at a little thrift store and I love the syle, colors, and the fact that it actually has labels (I have learned that trying to research a piece without lables is much more difficult, lol). Just from this piece I have learned about: Capodimonte, ewers, and putti. I don't understand (and am having a difficult time finding the specific label reference) what the E B or the "R" on the Capodimonte label means. It would be really nice to know who made this and circa. The label (on bottom) has obviously been off-set just a bit, not sure if this is an indication of lack of quality or if it's a genuine piece that had a factory misprint.

Any information or direction to reference materials would be greatly appreciated.
