Osterland

Prior to 1872, Carl Osterland's company operated in Freiberg, producing not only geodetic and mine surveying instruments, but also valuable physical instruments.

According to available data, another local company, Pessler (Päsler, Peßler?), was focusing at the same time on the production of compasses, hanging compasses, angled heads, etc.

From 1882 F. Weinland’s company was operating in Liebenwerda with a similar range of common geodetic instruments (theodolites, levelling instruments, plane tables) and tools (protractor heads, prisms). He also offered drafting tables, tracing paper, etc.
