581. Danish copper serving can. Marked “5” so I would presume it to be 5 liters. There is an engraving of King Christain V, who was monarch between 1670 to 1699 and was the eldest son of Frederick the 3rd. It is also engraved on the top “Math Loch Skal Land Bygges”, “by law shall land be built”. H. 9in., W. 6 1/2in(22cm by 15cm).
