letter scale, maker Jakob Maul
JMAZ is written on this letter scale. This is the abbreviation of Jakob Maul Aus Zell. The maker is Jakob Maul from Zell in Germany. This letter scale has a special zero adjustment. The entire scale can be skewed on the base to set the pointer to zero. This adjustment mechanism is described in the German patent DE555627. It was granted on July 25, 1932 to the company Jakob Maul from Zell. The purpose of this adjustment mechanism is to avoid scratches on table tops. Common zero adjustment screws apparently caused scratches. This scale may be of a much more recent date. The scale has a capacity of 250 grams. The scale has a stripe for every gram up to 150 grams. Above that there is a line per five grams. Each ten gram area is divided in half by a checkered band at the lower edge of the scale. Various JMAZ scales have been shown before, see for example this almost identical chrome letter scale, and this 100 grams version. The bottom of the base has a foam layer on cardboard. The scale height is 20.5 cm. The base measures 11 x 8 cm. The letter tray 9.5 7.7 cm. The measuring scale is 16.3 cm wide.
