![]() letter scale, on Erhard & Söhne decorative dish | The special feature of this letter scale is the decorative dish. The scale mechanism is known as model Fertig by Philipp Jakob Maul from Hamburg, Germany. The Fertig patent DE228054 dates from 1909 and became public in 1910. Elsewhere on this website there are other versions of Fertig scales, see for example this one with links to other Fertig scales. | ![]() back of the letter scale |
with curved brass bands ending in leaves, there is also an Erhard scale base with a straight square pattern of brass inlaid in wood, see the photo lower right on this page.
The scale is 140 millimeters high, the letter plate is 68 mm round, the diameter of the decorative dish is 98 mm, the dish edge is 15 mm high. The weighing range is 100 grams with a stripe of measure per gram. The values ??0, 15, 20, 40, 50, 60, 80, and 100 are in numbers. On the pointer arm is the abbreviation DRP (= Deutsches Reich Patent). The pointer arm is weighted at the end with a brass round rod, the M logo of Philipp Jakob Maul is on the front surface, and in very small, barely legible letters Fertig. The dish is assembled, the intarsia part is a separate part that is clamped on the dish bottom, see the photos at the bottom of the page. The photos show the still unpolished scale, also a letter plateau and indicator strip were missing. The letter scale is made complete and polished again. Below some more images of this beautiful special Erhard & Söhne letter scale.
