Bickham Script Pro  Sugerida por pilaster 

'ezier' is Bickham Script Pro (alternates for the 'e' and 'r'. Custom 'B' or possibly from another script.

Thank you pilaster you got it right.

It would be great to also know the letter B or closer font to that.

Just been having a play in Illustrator and the 'B' Is Bickham also. It's made up of an alternate cap 'B' and decorative swooshes that are also part of the fonts glyph set. If you look through the glyph set, you should be able to reproduce the 'B' by combining the corresponding glyphs (though this will involve a little adaptation of the glyphs).
