Hi Simba,
to add to the can of worms...
Here is a photo of the bowl that my large blue figurine came with (which I don't have on display with the figure because its a whopping 31cm plus in diameter).
Now I have seen this bowl in a smaller size with a smaller seated lady.
I poked around in my display cabinet and pulled out the smaller figure in the photo. The smaller figure is an exact scaled down version of the large one. Hands, hair style and length,leg position, feet number of folds in the draped cloth, bark effect on the stump, all the same. Although having said this the mould marks on the smaller figure are in more to the rear instead of prominently forward like the large one.
I wish I could remember where I have seen the smaller one attributed!
As the set of bowl and large figure were purchased secondhand I can't be 100% sure it is the original bowl but scale and colour are correct to my eye in natural light (photos taken with flash as its a dull day here).
Cheers
