yes, it is an event ship (ebb1)

and

no, I don't think anybody has it so far i know in kaiser server, probably we will see it if it will be a drop prize for an event in the future

I acquired one yesterday. It has very little room for weight. I can not put sailors and a decent engine at a time. Allows to put weapon 13.5 "/ 30" R ". The size is similar to Ammiraglio di Saint bon.
