From what I can see from the op pics it doesn't look right to me. The base looks like the pontil is moulded not polished and the colour is washy.
I don't know where the story about the original mould being used came from but that is incorrect. The mould may have been sold but not used for these copies.
The colours were willow, cinnamon, indigo, pewter, tangerine, kingfisher, meadow green and aubergine
