Nice original 1930s Melitta Nr. 102 Schnell-filter Deutsches Reichs Patent coffee funnel for 4-8 cups. You can actually still buy Melitta funnels at many American grocery stores. This is a more rare example, as it was designed for speed with extra holes. These have become very desirable in the past few years as vintage lifestyle people have started adopting them. This one is the pre-war version and in good condition. It just needs cleaned up. I use one of these as my everyday coffee maker. It just rather nice to think that my coffee maker is 80 years old and still doing its job. Its also fun that the filter are not only still available but still sized the same way. Just buy Melitta 102 filters.
