Unusual Brass Copper and Silver Stein or Mug

This is a very unusual unique stein or mug that is made in India. The outside is brass with a zigzag band made out of copper and the inside is silver. This is a very heavy quality piece of metalware. It measures 4.75 inches tall and and is 3.25 inches across the rim. It is in very good condition, no dents. I did not try to polish it as it has a nice patina on it. I do not know the age. It is an auction item. It does have a label on the bottom made in India.
