Jug with incised mark on the base

This stoneware green celadon colour Jug has a lightly inscribed mark on the base, can anyone ID this? Many thanks

I thought it might be Tremar (or Briglin) pottery, until I scrolled down & saw the mark !!
Someone on here will probably recognise it.

Thanks abstract toad, I have had this a few years and would really love to know who made it - keeping fingers crossed someone here recognizes the mark.... :)

I’ve edited the title because it’s very much British Studio pottery, without any distinct Asian influence imo . The glaze is more likely one with a touch of copper in it rather than a true celadon
