The more I learn it seems the less I know

Picked up this beauty at the local market today weighing in at nearly 4kg!  Sadly at some point it has had a top corner damaged but still I think an impressive piece

Nice glaze round the top. Slab-built, with the decoration derived from string or twine. I can't make out the mark on the base so not sure what monogram to look up. However as its a handwritten mark, it might be a hobby potter, in which case it won't be in the marks book.
