unfolded pocket scale
This penknife sized pocket letter scale (in German: Taschenwaage in Taschenmesserformat) was designed by Dr.-Ing. Franz Adler from Teplitz-Schönau in Czechoslovakia. A German patent was granted August 9, 1934. The specimen shown was produced by Jakob Maul. It has the JM mark at the back and also its own model name POCCO. Other specimens have also the letters D.R.P. added below the model name. D.R.P. is the abbreviation of Deutsches Reich Patent, indicating a German patent was granted. Up to 20 grams each gram has a stripe of measure. Above 20 grams there is a stripe per five grams. The weighing range is 50 grams. The pushed in, folded pocket letter scale measures 75 millimeters long and 33 millimeters wide. The front plate of the scale has a chrome trim. The drawings of the patent show the design is mirrored in comparison with the actual implementation. There are also some minor differences, such as the suspension of the letter clip and a somewhat different contour of the scale housing. Alongside this black laquered version also a dark red version exists.
