Help request for any information on this red clay pot

Good Evening,

I picked up this lovely a few weeks ago (at the tip) Yes I often source there whilst on a mission.

Its a nice solid, well made and quite heavy piece in red clay. The colour and the design would indicate 1960's (blacky-blue and cream) it almost looks like spongeware but Im not convinced it is, its smooth to the touch and has thin fragments of a gold coloured shell. I cant make out the signature its too weak despite various lights and photography settings.

22cm high and 14cm wide

Any help would be great.

Thank you

Emma
