Four cases of technical drawing instruments and compasses made of brass and steel. The cases, in different sizes, are made of imitation leather in different tones. The interiors are lined with velvet. They include compasses of various types, adapters, nibs, drawing pencils and a square. One is imprinted with the famous German Richter brand (also known as Chemnitzer Schul Reisszeug). Another is from the prestigious brand of scientific instruments Cornelius Knudsen, based in Copenhagen (Denmark). The cases retain all of their parts, in functional condition. Cases with wear and tear typical of use and of the period. The damage does not affect the condition of the instruments.

The Emil Oskar Richter company, founded in Chemnitz in 1875, manufactured a large number of machine-made drawing implements. In 1892, the company founder patented his "flat punch", which further simplified production and, at the same time, guaranteed the quality of the industrially manufactured precision punch.

Cornelius Knudsen gained international fame and his instruments were used on several polar expeditions. The company was founded on March 10, 1838 by Jens Cornelius Knudsen (1807-1879). At first, the company was based in Gråbrødretorv, but in 1845 it moved to a building on the corner of Købmagergade and Løvstræde. Knudsen's son, Theodor Valdemar Cornelius Knudsen (1844-), served as a cadet on the corvette Heimdal in 1860. He befriended Prince William, later George I of Greece, who also served as a cadet on the ship. Back ashore, he initially worked in his father's workshop and then attended classes at the College of Technology. He ran the family business from 1870 and continued it alone after his father's death. On May 27, 1884, he changed his surname to Cornelius-Knudsen. From 1895, the company was headquartered at Købmagergade 15. The old building was replaced by a new Domus Optica in 1946-1947. The product range covered optical, navigation and surveying instruments, planimeters and telegraph equipment.
