Sold for A$35
Doulton & Co Ld / 43 / Lambeth. . Ink. Stoneware. Penny ink with a pouring lip. 61 mm. 1890s. (Added 13/10/22 - at least one of these exists with a label for dental mercury. A bottle that may have had a number of uses but given they went to the trouble of a pouring lip a higher value use makes sense)
Near Mint. (9). 2 x 2 mm glaze flake on the shoulder. Some rust under the base. Hard to believe they went to the trouble of putting a pouring lip on one of these little guys. Estimate: $10-20
