Please help me to id this stoneware pottery vase

Nicely potted stoneware studio pottery vase, very heavy, height 15cm high.

Any help or comments would be appreciated.

Thanks Mark

The mark suggests a hobby potter and with you saying that it is heavy and with the glaze having gone wrong suggests that too.

I agree about the mark and it being heavy, but I like the way the glaze has "gone wrong" and wonder if it was intentional.

It seems to me to be a very well potted vase and the glaze does look intentional. Because of the quality I have discounted the possibility of it being a hobby or night school creation. It is only an opinion.
