sorry for the late reply...
I believe this object is an early Art Nouveau piece...
the Buddha does show thai influence...but...the four armed hindi goddess or god{wear precludes identification from a photograph}
Buddha is a state of being, not a god or diety..so several Buddha can be presented together, though, the individuals flanking "Buddha" are probably bodisativa...Buddha who have come back to help mortals...
so, the point is I do believe this is an early piece...pre 1900...or close to...pre 1920..but I would need hands on to identify any closer...
hope this helps.
