Ancient Pottery

A lot of repairs with clay. Any idea of the culture?
Thanks

 

I was researching something else today and came upon “ Ban Chiang” pottery. From what I saw online it could be it.
Here is different shale but similar repair with clay:

Ban Chiang vessel with basically similar shape at Linden Museum, Stuttgart:

But note the crisper transition between body and neck of the vessel. And the surface of yours appears suspicious/manipulated (and not just the repaired areas).
In 1982 a University of Pennsylvania archeologist reported "the production of fake pottery in neighboring villages. Made from local materials, these fakes were indistinguishable from original pieces. Some were composites of old and new material."
