Belleek Ireland Black Mark Sugar and Creamer Ivory Porcelain Circa 1926-1946

Belleek Ireland Reg N 0857 porcelain creamer and sugar bowl. Black mark identification on bottom: Belleek Co Fermanagh Ireland Reg N 0857. According to the Belleek website this mark was used from 1926-1946. No chips cracks or repairs. The outside is ivory and the inside has a pale yellow hue. The color is inconsistent on the inside. There are a few dots on the exterior. I cleaned these but did not scrub the spots as I’m not sure what they are. Excellent early to mid 20th century Belleek.
