This letter scale is a black enamelled tin successor of the columbus bilateral. Originally the complete mechanism was made of brass. The scales were not easy to read. Here the readability is improved by using white figures and white stripes on the black surface. This scale of Philipp Jakob Maul has a double lined M-logo. In the lower range of 0 till 50 grams each gram has its stripe. The upper scale has a division stripe per 5 grams. This scale ranges from 50 till 250 grams. This model has a handy loose aluminum bowl, of which the lower edge fits into the aluminum saucer. The scale also exists with a plate design that is often applied. Its form is a rectangle with rounded edges, with small spherical shaped elevations at these corners and a slightly lowered middle part.  Also specimens with different ranges exist: for

instance 250g with 1000 grams. Other variations show brass colored parts instead of the chrome colored parts applied on the scale shown here. The double lined logo isn't applied on all the variants. Below some more photos of this letter scale.
