A Spode blue and white pottery plate in the Union Wreath 3 or Union Spray pattern. Thanks to Gay of Owens Antiques on Ruby Lane for identifying this for me.
The central pattern joins the rose of England, the thistle of Scotland and the shamrock of Ireland in a tied bouquet, and around the border is the daffodil of Wales.
The plate bears an impressed SPODE mark with the number 44 (oddly reversed). This mark was used from circa 1784 but the pattern dates to circa 1825. The plate also has SPODE printed in blue and another mark, badly printed, which could be B.
The mark was verified in The Encylopaedia of British Pottery and Porcelain Marks by Geoffrey A Godden, and the pattern in The Dictionary of Blue and White Pottery 1780-1880 Volume 1 by AW Coysh and RK Henrywood.
The plate shows the expected fine crazing with a little light staining within the crazing. It measures about 9.75 inches (25cm) in diameter. There are three small kiln marks, close to the rim on the underside.
