Chinese, Japanese, Thailandese teapot

I paid €2,50 for this Teapot and it's worth every centime of it. But it puzzles me:

The finish is good.
The colour is good.
The feet are unglazed on their bottoms, although the bottom of the pot is
glazed, so I suppose that signifies it is porcelain.
Rim of the pot and the lid protrusion are hexagonal; but lid protrusion is smaller than the hole and it turns through 360 degrees.

What puzzles me is that although the base says it is 'hand painted' in French, and through the glass it appears to be so, it is shy about the country of origin.

All other teapots of this type are quite proud to give this information, and they are of course required to do so.

So was this €2,50 teapot made before 1891? And is it worth a great deal more than €2,50?

Opinions please.

 

could be made out of Asia based on mark
only Asian style

 

It is very new, country of origin was probably on a sticker, now gone. Most likely Chinese, or somewhere else in that neighborhood - but again, made yesterday or so.

 

I appreciate that the country of manufacturer could have been on a sticker; but why 'peint a la main' under the glaze, and in French?. Surely they would have done a 'Made in ...' stamp at the same time, unless Company 'A' is making a generic teapot for other companies to market in their own name, i'e. sticky label. Has anybody heard of that.
