F. Winkle & Co. England BYRON Ironstone Brown Transferware Toothbrush Holder?

Vintage F. WINKLE & Co. brown transferware vase or toothbrush holder, I'm not sure exactly what it is, but it's in very nice condition.. no cracks or hairlines, chips or crazing. I don't see any flaws or issues. The bottom of the inside looks sort of gritty, but it's just how it was made, it's not a flaw. Also, there's a dimple on the bottom where the maker's stamp did not make contact and it's a white spot that might appear to be a chip, but it's not, and it is fully glazed. Very nice condition!
