Wester & Son Quadruple Plated Water Pitcher

This is an interesting piece from my collection. It is quadruple silver plated by a Wester and Son. There is a white hard metal with the stamp 206 on the bottom. The knob on top is reminiscent of a rose bud. It is a slim, refined piece, though tarnished, some elbow grease could make it shine; though I personally prefer the current patina.
