Model of an Optical Telegraph, Model of an optical telegraph on octagonal base. The telegraaf consists of a mast with three rotating arms, these consist of a trellis to keep their weight low, and are black on the one hand, white and cut-away on the other, which only serves as a counterweight, so that this end is practically invisible from a distance. Each arm has six positions. A half-octagonal hut with a pointed roof has been built on the base, which shows the inside and the operation of the signal mechanism., anonymous, 1800 and/or c. 1806, wood (plant material), iron (metal), glass, rope
