Ca. 1950 - Germany Nice and working three-dimensional model of the rotating earth around the sun. This tellurium is made of metal and presumably made in Germany, in the 1950s. The sphere above the central foot contains a lamp; This mimics the sun and shines on the earth. In older copies the sun was mimicked by a candle. With the pendulum the earth revolves around its axis; This in turn leaves turns the moon around the earth again. For example, days and nights are simulated. With the sling the earth revolves around its axis, you can see the seasons by means of the signs of the Zodiac and the seasons on the horizon ring under the lamp. The tellurium is given the German-language chart under the lamp, made for German schools. This model (dimensions when Moon is approx. 85 cm long and 44 cm high in the furthest position), given the old age, in good condition and everything works. Very decorative! Can be used as ambient lighting. Also see the pictures, they are an important part of the description. Given the weight, dimensions and fragility of this model, pickup is desirable. Shipping (insured) can also cost buyers (see shipping costs please) and risk, in consultation with seller.
