Vintage Simplex Copper kettle. Looking at other examples, I believe this could be a stove top whistling kettle but I never used it myself and cannot guarantee it will whistle! Looks like it may have had a piece of copper covering around the coil too which isn't there.
Please see photos- one side of the kettle has a large dent, a small dent on the lid and there is extensive limescale to the coil and inside, although I'm sure the right limescale sachet could sort this!
Appropriately 21.5cm tall.
