Miniature Wood Stove Porcelain Teapot

We bought this lovely miniature (10 cm long) several years ago in the Saturday market to a seller that is very polite, it is always a pleasure buying something to him o just a little chat.
We are sure it is old, and most probably was never use. It is a sort of container (instant coffee, salt) because it has a stopper and a toy. I found several similar, but newer and seem they all were produced by Paul Cardew. Ours seem of Vieux Paris porcelain by the paste and the gilt.
