others might already know this particular shape, but it's new to me - don't get the feeling that Stuart did much in the way of plates in comparison with other shapes.
In Benson & Hayhurst 'Art Deco To Post Modernism', this cut design appears to have been not uncommon from the mid 1930's to early 1950's, and may have had its origins earlier still in a design from L. Kny. These authors suggest that the border design is known locally as the 'Waterford Pattern' - it may be that this 'locally' was intended to indicate the Stuart factory area, but I'm unsure.
As with most (if not all) pieces with this design, this one is marked Stuart England.
Examples with this pattern are seen in a variety of shapes, although this plate doesn't appear in the above booklet, however bowls, footed salvers, comports and vases are shown.
The 12" shallow bowl is quite an impressive piece, and I've had both that size and the slightly smaller one at 10.5" - the larger one is shown in the attached picture.
Thought I'd post a picture of this oval plate as it doesn't appear in the booklet, and might be of interest to collectors who may not be aware of this shape. The longest dimension is about 11" (280 mm).
