You have interpreted correctly m - Said was, I believe, commissioned to make a chess set, and continued making these Knight pieces afterwards. I have seen several really wonky ones, some with great big bases like yours. They have also been seen with blue tops, (as in outer casings and head) in reds, and in browns.
In the more common blue ones cased in clear, the bases are sometimes random yellowy bits on blue, or with vertical yellowy stripes on blue - kind of sea urchin-y. I've also seen them up to about 9" in height - with big fat bases like yours.
The info. I had about their origins has not been altered or corrected, to my knowledge, and I wrote the bit you quoted.
I suppose the best way to clear all this up would be for you to write to Mdina with pictures of this beast, and ask Said himself!
As it's his work, I imagine you should get a reply. :X:
