William Newland

My only piece, a 13 inch bottle-vase.

A bull circa 1984.27 cms long.

A 1952 earthenware dish with 'Horse and Rider design. 29.5 cms diameter. Painted mark.

A large earthenware dish with rooster design. 43 cms.Incised mark and dated.

A large earthenware  dish with fish design. 1950's. 39.3 cms.

Croker is right though. James Tower, Margaret Hine, William Newland, and Nicholas Vergette did the ceramic course in the London Institute of Education in the late 40's. Equally, all used Tin glaze techniques in some form or another. Hence the association.
On t'other hand the Picassettes stayed in London, and produced some good painterly ceramics and became part of that 50's London culture Coffee Bars and all.
Whereas James Tower taught at Corsham,Bath throughout the 50's. As you say though Studio, he produced a quality and uniqueness of work that was more Fine Art than studio pottery. There is an interesting book on him worth having a look at.
There is a clear link, but not a very strong one.

William Newland bottle in the Bill Ismay collection at York COCA

There are four almost identical bottles in the V&A collection dated 1958/59.

Yes they're all over the place! A pity they're a bit plain.
Still the only piece I've ever come across though.
