Is this a Winchcombe teapot?

I have this teapot which came in a mixed lot which included some Winchcombe and Coldstone pieces. It seems to have no marks I can find. Looking around, the combed pattern seems similar to some Winchcombe pieces - but could anyone be certain without a clear mark?

Thank you,

Chris Harries of Coldstone did his apprenticeship at Winchcombe 1948-51. It definitely looks like a Winchcombe teapot, but without a mark it is simply impossible to give a totally definitive answer.

Thank you. I am loving the glaze. It was mucky and just 'brown' when I picked it up and all those lovely shades and lustres came out with the washing up liquid.

Above is a link to Page 2 of the Ray Finch thread. Scroll down, and you will find three Ray Finch teapots from the estate sale of Harry Hprlock Stringer's ex-wife. The third one is a very similar glaze to this one. I

Thank you. I found a jug on another site/ blog with a similar glaze too. But I appreciate it's not possible to be certain. How do item miss being stamped in the biggish lotteries?

Sometimes the clay is too dry to stamp. Might have been at the end of a long line of pots and teapots they made that day.
