letter scale

This is a letter scale of Philipp Jakob Maul from Hamburg, Germany. His M-logo is engraved in the frame above the main pivot. The scale is chromium-plated. The enamel scale has a stripe of measure for each gram, that is a good many. the weighing capacity is 250 grams. The chart is placed concav, this is specified by text and eye-logo at the right end of the scale. Partly readable is the indication MONOGRAD and below this D.R.G.M. This is the abbreviation of Deutsches Reich Gebrauchs Muster, a model protection, quicker and cheaper than a patent registration. I don't know whether or not Monograd is a registered name or model. Below some more pictures of this letter scale.
