This coffee grinder is in good working order. The brand is unknown but the sign of DRGM indicates that it was made in Germany during 1891 to 1945. Nevertheless, from the look and material of the coffee drawer, it was most likely produced before 1910 as after this period Germany has introduced lots of wall mounted coffee grinders with glass container. The coffee grinder is supposed to be clamped on of flat surface i.e. a table with the help of a metal screw clamp at the bottom of the grinder. There is unfortunately a line of crack on the hopper, but nevertheless still sturdy.
