The Prado 250 (it was the 1950 renamed Parvo 250) had a triple-walled lamp house, lenses of focal length from 85 to 150 mm, and different attachements for micro-projection or with a micro-aquarium.
In 1953 the colour changed to grey. 1954 the stubby base was replaced by the elegant base.
Lamp: cine socket bulb of 250 Watts, In 1954 the more powerful Prado 500 was introduced, a built-in blower in the base supplied the cooling and now lenses up to 250 mm were offered. Longer focal lengths were available on request.
For lenses of 200 mm or more a special long base was offered.
For all Prado (250/ 500) a magazine changer was supplied. Leitz offered the Prado 500 until 1968, then the Prado Universal replaced it.
