Antique Large Tibetan monks hat ewer

Selling this antique Tibetan monks hat ewer,China or Tibet, 15th-17th century This is a very old and beautiful piece. It is bronze and has semi-precious stones on it. As can be seen by the photo one of the decorative squares is missing. As can also be seen, this originally had a leather strap that they carried the jug with, the leather is missing but there are pieces of it still attached. The pot/jug weights almost 5 pounds and measures 9” high at its lowest point and 12 3/4” at the point in the back and 8 &1/4;” in diameter. I have never seen one of these anywhere. The jug has 3 semi-precious stones, possible red jasper?
