Very rare clockwork tin litho Tower Railway manufactured by Johann Höfler, Germany (U.S. Zone). This unusual toy comes complete with every one of its original pieces plus some more pieces then is stated in the content list, plus die cast metal keys and instruction sheet. Best of all it includes the original early post-war box with cover print. Tested and works. Toy is characterized by its double circular loop, wooden tower, and its clockwork wind-up rail car which reverses direction automatically. The position of two brackets protruding underneath the car changes its direction, forward or reverse. The sleepers strike the bracket underneath the car to change its direction. The rail cars and stations are marked "Made in U.S. Zone Germany". The box is an old style, two piece, narrow walled pressed cardboard. Corners are held in place with right-angled staples. The cover features a full color illustration of the toy in an imaginary setting with groups of large red speckled mushrooms. The only marking is the JH shamrock in the upper left corner.
