Lidded Pot with no marks

I know it’s a tall order but I’ve always loved this “minty” pot.

Skegness or Briglin? But without a mark it'll be difficult to be certain; they weren't the only potteries to use this combination of clay and glaze

Skegness was my first thought. The glaze is very thick on the underside so it's possible that a mark has been in-filled. I've seen a few pieces of Skegness with the mark on the side of the body at the bottom.
It might be worth going around the bottom and sides with a strong torch; it may be possible to see the 'ghost' of a mark that way.

Looks like a Briglin base, although also similar to Skegness.
