Help with a Thai(?) or other Asian sauce dish(?)

So I got this in a lot recently. I cannot seem to find anything definitive on these, other than finding this Cornell Museum object and other related ones in the same museum, I've been unable to find anything else. When searching for Thai sauce dish or Bencharong ware I can only find other examples from that same Cornell Museum.

I'm assuming this means that Cornell incorrectly attributed this. But does anyone know what it is? If it is indeed Bencharong ware, does anyone know of any auction records for anything similar? All my searches have come up empty.

I have about half a dozen of these, all of these have very similar markings, and slightly different sizes. None seem marked on the back, however a lot of them have tape residue (I think the previous owner mounted these on the wall)

Any help would be much appreciated!

So am I, it doesn't look like the usual Benjarong ware to me.
The decoration looks Chinese, maybe Vietnamese? Could be a type of provincial ware that isn't easy to find.

 

There are a few similar on this site but I as it's not written in English the English translation isn't too helpful.
