William Hutton silverplate teapot

Does anyone know how much this teapot might be worth? I can’t seem to find out what the B and P mean or when it might have been made. Any help would be appreciated!

BP stands for Britannia Plate; i.e. electroplate over Britannia metal. It probably dates from the early 20th century and has very little commercial value especially without the rest of the set (milk jug & sugar bowl).

Great, thanks. That’s all I wanted to know!
