1830's to 1900's Thailand Prayer Box

Hello, 

I came across a very unique item in an Antique store, it struck my eye and i bought it on the spot. I have tried researching with Zero luck finding anything on it at all. On the bottom of the one engraved elephant it says "Thailand prayer box 1830's- 1900's" I cant find a thing from any period of time that looks even close. It is hand carved work of art to me but it would be nice to know if it has any value at all. There is a carved peacock on top, two dragons on side of the top of the box, two elephants on the bottom all hand done and removable to get to the two back compartments. The center has a movable wall turns to see a place where you can put several incense. There is some carving on the box itself as seen in photos i post. Any input would be greatly appreicated. 

Thank you
