Carved Walking Stick, Dragon Head Handle with Loose Ball in Mouth

An unusual carved wooden oriental walking stick, with the handle in the shape of a dragons or serpents head with a loose ball in its mouth. This vintage carved wooden walking stick is beautifully made item. We believe it to date from the early 20th century. The carving runs along the whole length, with the handle of the walking stick in the form a mythical creatures head - I think it is a dragon, but could be some sort of serpent. In the creatures head is a loose ball that moves around. This must have been formed during the carving process as there is no way it could have been added afterwards.
