asian wooden carved smiling person (buddha?)

I bought this wooden carved smiling person (a buddha?). It is missing a piece on top (left side of his head) and the wood was very dull. I used some beeswax and polished it, so he's got his natural glance back. I like it very much.
Can anyone tell me the origin, who this is and how old it may be? Does anybody know what is he holding in his hands?
Tnx for your answers.
