A plain white background would make it a bit easier to see, but I think you're on the right lines.
i own the lollipop and the small bowl at the bottom in the link there, the blue and olive-y coloured one.
I don't know if they're supposed to be the same colour schemes, as the lollipop has white in it that my bowl doesn't. The white in the lollipop is not so "bitty" as it is in your bowl, it's much more "cloudy", but I have found some "bitty" bits towards the bottom.
My bowl has a sort of flat bottom. It's shiney, but not polished flat - it's all lumpy, so I think it's heat finished. The triangular black label is there and I can't see under it.
The lollipop has a square, clear plastic label.
Looking at my bowl, it does have that strange ring/air bubble in the middle of the bottom that yours has.
Small, early and very thick IoWSG bowls do tend to vary a lot in the execution of the construction. I would not really expect two to be exactly the same.
I think it was only later they prescribed exact dimensions, which they measured with calipers during the making.
There is a bulge in the middle of the bottom inside, over the bubble.
Overall, I think it probably is Petit Fleur.
