Help Identifying Marks On Teapot, Circle and Cross

[mitchkel]

Hello,
I am looking for help identifying this teapot. It is quite lovely. It is marked on the bottom with a circle and a cross that looks Russian. It also has the initials WF and the number 5.
I would appreciate any help you can give me!

That might be an Old Sheffield Plate mark used by Walker, Knowles & Company, 55-57 Burgess Street, Sheffield, England.
Founded in 1836. Started electroplating in 1853.

Pat.
