egg scale

This egg scale was made by Philipp Jakob Maul from Hamburg in Germany. This design also was sold as letter scale, see this little concav letter scale. The letter was then placed on a round plate with a lowering. This round plate is replaced by an egg-cup to transform it into an egg scale. Like the letter scale, this egg scale has a weighing range of 100 grams. The scale has a stripe of measure per each gram. The egg-cup is aluminum. The black painted frame is folded out of tin. The M-logo of Ph.J. Maul is placed at a strip of the scale mechanism.
