Help with an old blue and white pottery urn with handles with markings that look like a number 8

Hello fellow steamers, following on from my last blog regarding help about an Hungarian artist J V Breznay belonging to my late father in law. We have now come across an old Beautiful blue and white handled urn with a unusual marking on the base resembling a figure 8, Looking through the mass of literature and markings on the World Wide Web and too no avail, I am hoping that someone on steemit may be able to enlighten us on a makers name, if you are aware again of any of your fellow steamers who may be able to help I would be mighty grateful
Regards Mark
