The Wigomat was taken into production in the late 1950s, until the early 1960s. This is the world's first electrical device that makes coffee. A piece of history. The device consists of a glass reservoir for a maximum of one litre of water. Underneath the reservoir there’s a heating element that heats the water so that it bubbles up through a riser to the coffee filter. This filter is filled with ground coffee on top of a paper round filter. The coffee drips into the glass coffee pot, that is underneath on a hot plate. The filter reservoir shows a small tear in the glass work. Although this has no effect on making the coffee, the water seeps downwards, this device has a lot of history and will therefore serve best as decorative piece. See photos for details. Will be shipped with track & trace.
