inkstand with letter scale on a black glass plate
This ink set has two removable inkwells and a letter scale mounted on a black glass base. In addition, there are two supports on which dip pens and other writing utensils can be placed. On the bottom of the glass plate, four rubber feet at the corners ensure a scratch-free setup on the writing desk. The scale is a small Columbus bilateral letter scale by Philipp Jakob Maul. The weighing ranges are 0-20 grams and 20-60 grams. The name Columbus is on the back of the stand. On the front are two German patent numbers DRP 167192 & 184690 and an Austrian patent 25487. There is some more information about these patents earlier on this website, see this Columbus letter scale. The same arrangement of two inkwells with another letter scale on a black glass base plate also exists.
