Antique Porcelain Sink Strainer BB New Stone 6815 Blue Rings 8.5”x12”

Antique white porcelain sink or wash basin strainer with triple cobalt blue rings and a central drainage hole. Impressed “BB” and “New Stone” on the back, with model number 6815 and a hand-painted decorator’s mark. Measures approx. 8 5/8” x 12”. Attributed to Minton, British-made circa 1850–1890. Shows signs of authentic use — including some glaze wear on the rings and a couple of small edge chips — but no major cracks. Solid overall condition for its age. A hard-to-find and functional antique for farmhouse decor or collectors of early plumbing and ironstone.
