1960s vase with JT incised mark

Asking for a friend. I have seen British pots marked in this way from the 1960s where the number has indicated that it was the 4th pot the potter had made in the year. It was found in London and so might not be British.

SP for me the odd thing about this one that hits me immeatiatly are those x6 lattice scratch mark as decoration. They look like a tiger had a go at it, and he as not a happy tiger at the time. Not pleasing on the eye and just odd?, not seen before, uncomfortable.

Student piece imo

This vase belongs to someone that I have known for probably 30 years and he's in the "rag trade" but collects art, design and pottery as a hobby. He lives in the Hampstead area of London and gets most of his pieces from local house clearance people he knows, who tend to offer him paintings and art object. Therefore it probably came from a "good" home. I can see why you all feel that it's a student piece/hobby potter and you could well be correct but to me it just seemed to be a little better than that. However, I am not saying that you are all wrong and I'm right.

I had ruled out Janice Tchalenko but I came across a name of a CPA member from the 1960s called John Turner but have been unable to find any examples of his work. Therefore, my query was to see if anyone knew anything about his work.

it looks to have been vandalised rather than decorated

If it came from a good home then the previous owners might have been able to afford to take up pottery as a hobby.

They could also have bought it for 50p in a charity shop but, knowing the area, it would more likey have been £3.

I like the shape and glazing. Can’t help with an ID tho’.
