This lantern was originally mounted on the former Emden Kaap lighthouse of Rottumeroog, an island in the mouth of the Ems River at the Dutch-German border. In 1956 it was transferred to the 1912 Schilbolsnol lighthouse near Horntje, the seaport at the southern end of the island of Texel. When that lighthouse was replaced in 1977, the lantern was donated to the Shipwreck and Beachcombing Museum in Den Burg. (according to Russ Rowlett)
