I really don't know much about this copper beaker , i believe it is antique and hand beaten , Middle Eastern or Indian .
I have not polished the beaker but i did give it a good wash in soapy water as it had been on a kitchen shelf and was very greasy .
I am also selling a second beaker and am happy to combined postage .

Condition - no holes , splits or dents , looking down on the beaker it is slightly off round . Hight 5.25 inches , 13.5cms , diameter at the top - 3.25 inches , 8cms .
