Wächtersbach vase ?

I love this vase, the shape, the colour.
There is only a very faint impress mark, a beehive and a W to the base. It will not show up on a photograph
as it is under the glaze. This and the colour suggests Wächtersbach.
What do you think?

Possibly, are you sure it´a beehive ?
If W´bach i´d expect a form number on the base, at least.

Definately a beehive mark and a W. There is a trace of something else but the glaze makes it impossible to read. I don't even know if it is letters or numbers.
