This special version of Ernst Plank's 'Climax' for the U.S.A. and the
United Kingdom was called the 'Brass Climax' (1890). The lantern has a spherical polished brass
lamp house and a richly ornamented die-cast objective holder. Height: 22,5 cm. Suited for circular
slides and, with the help of the enclosed accessory, for normal glass slides too.
