Realistic glazed stoneware pig figure seal mark to underside...any ideas?

Beautiful realistically modeled stoneware pig, approx 6 1/2" length, with a semi-matte green-blue and brown glaze. Seal Mark to base has impressed or incised letters/characters. Possibly a J or T though could be chinese/japanese style character. Drawn a blank with usual reference books/net. Has anyone seen it or something similar before? Thanks

Can't make out the mark, but wouldn't be surprised if it's from the Far East.

Thanks Naomi, if that's the case will probably never find out!

I think it's probably British, quite a few potters do animal sculptures, if only the mark was clearer I think someone would be able to figure it out.

Mark might be a partial M
