Kettle, possibly brass but not sure. Household Ornaments Bric-A-Brac HARIASTAMP.
Is it brass or copper ? I have no idea, but seems more towards brass.
It is a very nice piece, and I am sure the metal will polish up very nicely with a bit of metal polish.
The height is about 3 " tall with the handle at full mast.
And it is 4" from tip to tail.
Sorry about the postage...that's what it will cost to send through Royal Mail.
