Old copper-style kettle, no leaks, antique, retro

【Product Description】
Thank you for looking.
This is an old kettle that was stored at my grandparents' house.
I am listing it for decluttering purposes, but I do not know the exact material or when it was acquired.
The entire kettle has an embossed texture. Based on its reddish-brown color, the green rust (verdigris) on the underside of the lid, and the fact that a magnet does not stick to it, I suspect it is made of copper, but I cannot be certain.

【Condition】
Water Leak Test: I filled it with water for a short time and confirmed there were no leaks.
Exterior/Interior: As this has been stored for a long time, there are overall discolorations, scratches, and dirt.
Underside of Lid: There is green rust, characteristic of copper products. Please check the photos.

【Please Note】
The handle is also made of metal, so it is expected to get very hot if placed over a flame. Please use a holder or similar item if you intend to use it.
As I lack specialized knowledge, I would appreciate it if those who understand that it is sold as-is and those who appreciate the aesthetic of old tools would consider purchasing it.

【Shipping】
It will be packed with cushioning material, placed in a recycled cardboard box, and shipped via Mercari delivery service.

While there are many unknowns, please carefully check the condition in the photos before considering your purchase. Thank you.
