There is old calcium build up around the beak. I did not try to remove it or spruce this item up. It will shine up more for sure. It looks like a very old form, note the carving markings from the original swan faucet sculpture prototype down the back.
The newer manufactured swans are much more perfectly stylized. This guy looks like an art nouveau era swan faucet piece.
This is a single faucet piece for sale.
