Mappin Brothers ewer/pitcher

I would like to find out the date this was made and exactly what it is called. The bottom of the pitcher has inscripbed Mappin Brothers 222 Regent St & London Bridge. There is a sun before the name. So this is prior to it being Mappin and Webb. Below the name there is a number 3154 etched on it. On the opposite side of the bottom the # 30 is stamped. I am thinking about having it re-plated.
thank you
