Unmarked vase - indistinct mark found

Anyone any ideas who might have made this vase?
No marks unfortunately. Aprox 18cm tall and 8cm diam at base (about 9cm at widest point).
Thanks for any help.

Tolcarne maybe? That undulating glaze effect, down to bare stoneware.

Thanks, that does look like it could be.
The clay on this one also has a lot of black speckles, which shows up on the base of several of those as well.
Also, it has a lot of small black 'hairs', so may have had black felt attached or just been stood on black felt for a long time?


Whilst doing this reply, I've had a good look around the base and lower edge with a hand lens and found what (to the eye) looked like a smudge, but under the lens looks like possible letters? But it's tiny - 3mm x 4mm. On the lower edge of the vase, not the base. Shown both ways up. It could be a triangular mark, but I'm not seeing the TP. One looks more like an S to me??
