Another Egg Shaped Pot with unrecognisable mark

Hallo all, I hope you are well.
This small pot (4.25 inches tall) has a very distinct egg appearance. The opening represents the cracking of the egg:sadly (and realistically) there is a tiny chip on the edge of the opening.
The mark is pretty clear but I'm not certain of the letters: there could be an 'S' or 'J'...equally an 'H' or 'T'. Can anybody please identify this maker's mark?
Thank you
Jack

Thanks for this Philpott, its very interesting.
There is a lot to read on this site about Alan Wallwork! I was unaware of his work, but it is clear he was held in high esteem.
I recognise the influence Alan may have had on my small pot: his obituary in the Guardian (20/11/19) has a picture of a number of similar egg-shaped vessels.
Did I read in one of the posts on this site that there is an Alan Wallwork society?
Thanks again Philpott.
Jack.

There isn't an Alan Wallwork Society but Joe the Hat, who runs the .info site and is a member of this Forum is the nearest to "a society"! If you were considering contacting him for more information about your piece, I will save you the trouble, as I suspect Joe would forward your email to me. During Alan's lifetime, I persuaded him to have his first solo exhibition and held more exhibitions of his work than any other gallery.

While I agree with the "school of Wallwork" description I would say that the clay body and the method of manufacture tell me that it was not made by anyone that worked with Alan. Also I don't recall seeing the mark before.

However, it looks like a pleasant interesting piece.
