Aynsley Bone China Teacup/Saucer Underside

The item appears to be the underside of a bone china teacup or saucer, manufactured by Aynsley in England. The primary color is a pristine white, characteristic of high-quality bone china, which is known for its translucency and delicate appearance. The visible part of the item shows a raised footrim, indicating it is likely a saucer or a cup with a substantial base. The craftsmanship suggests a finely made piece, as expected from Aynsley, a renowned pottery company. The most notable features are the manufacturer's backstamp and an additional black mark. The backstamp is centrally located and reads "BONE CHINA," "AYNSLEY," and "ENGLAND," all enclosed within a decorative green crown motif. This specific mark, with the crown and the wording, is indicative of Aynsley's production between approximately 1934 and 1950, suggesting a mid-20th century style period. To the right of the main mark, there is a distinct black-inked symbol, which resembles a stylized 'S' or a manufacturer's decorator mark, possibly indicating a specific pattern series or a detail from the decorating department. Below the main backstamp, in black handwritten script, are the numbers "N663 / 5," which are likely pattern numbers, batch numbers, or internal inventory codes used by the manufacturer or a retailer. There appears to be a slight discoloration or light staining along the edge of the footrim, which could be minor wear, residual dirt, or a slight manufacturing imperfection. The overall condition, based on the visible portion, seems good, with no obvious chips, cracks, or significant wear visible on the back, suggesting it has been well-preserved. The bone china material itself signifies an item of higher quality due to its strength and bright white finish.
