Buddhist Bell on carved wood frame, Where made? How old?

Got this at an online auction for $20.00 I do not know where it was made, but maybe Tibet or Nepal, if I had to guess. The bell was cast in two pieces, very nice ring. It has a dragon going around the bell and each side of wood has 2 glass eyes looking, Any information or ideas would be appreciated. It looks good with my Buddhist statues. Thanks for looking!
