Melitta 101 Coffee Funnel Cone D.R.P.a D.R.G.M.
Original 1930's Melitta coffee dip filter cone number 101 for 2-4 cups of coffee. Marked D.R.G.M. (Deutsches Reichsgebrauchsmuster) and D.R.P.a. (Deutsches Reichspatent). Melitta has been producing coffee filters and these cones since the early 1900's and even today they still make filters for this 101 funnel.
This funnel is their Schnell-Filter model with more holes for faster coffee. It measures about 3 1/8" tall. It is in good condition, but it does need to be cleaned before use.
The advertisement in the photo is from the November 1940 issue of Frauen Warte.
