50p worth of questions !!

Hi
Anyone have any thoughts on this wooden panel ?

I'm thinking it may be Thai  but unsure what it would have been a part of. It obviously has some age . Ideas welcome - however vague!

I think you could be right with Thai. Is it big enough to be the back of a chair?

Oops forgot dimensions ! At widest 27cm .
It appears there may have been another piece fitted vertically from the top as there is a screw hole and a slightly depressed area although this could have been a recent addition.
My only thought is that it's a similar shape to the front of Thai spirit houses , could it be from a small version of these ??

Spriti house is definitely a possibility, although maybe a wall mounted one, rather than a whole four-sided one.
