Nice early 1800’s inkwell in similar style to the Wedgwood Basalt inkwell. Two quill holders plus main opening and additionl opening with original plug (plug appears to be of matching porcelain material). One tiny knick along top edge. There is an imprinted “3” on the base and I found references to both “Dudson” & “Robert Wilson” pottery inkwells that was blue (similar to Wedgwood blue as well) that had the same imprinted “3”. No other markings to help determine maker.
