Antique 19th Century Askos Jug Ewer Goats Cherub Nicholas Muller Sons 188?

Antique Askos Jug Ewer Goats Cherub Ornate Nicholas Muller Sons 188? 19th Century Bottom is stamped: Copyright by Nicholas Muller Sons 188? (I can't quite make out the final digit). One of the goats did come off. I did not attempt to reattach. Sold AS IS. It seems to be in pretty good shape otherwise. Please examine photos closely. It's quite heavy, over 3 pounds. Not sure if made of silver or another metal but is silver in color.
