Renaissance revival??? Unfinished Ewer? Wine/water goblet?

Hello,
i have this ewer-like thing. Its mounted 19 cm high and the widest part is 13 cm wide. it is cast in two pieces and then put toegether (seems). It weighs only around 500gr and this is why i think it's not bronze. Its not magnetic so i think its maybe brass or painted copper . it s dismountable. if you take it apart you have a kind of wine / water goblet. don't know if this was intended. Or its a unfinished ewer. it has something of reneissaance revival type thing and france like but maybe i'm wrong and it's dutch or german, italian made.

who can tell me something more about this ewer/goblet?
where was this made,
what period,
information about the symbols used on decoration,
is it a genunie pice or a fake one
material used

thank you in advance

 

If needed i can post a few closeups
