Hora Pasera. Hamburg: Janos Bartl, ca. 1935. A pocket watch and alarm clock are placed in two tall nickel plated stands. Doors on the stands are closed. When opened a moment later, the clock and watch have changed places and can be removed from the stands. 22 ” high. One small screw lacking, minor wear visible, one watch lacking glass; minor mechanical issues; good. Uncommon. The Bartl and Davenport firms developed a strong business relationship in the years leading up to the Second World War. A large number of the metal props sold by Davenports – as well as thousands upon thousands of small pocket tricks, most intended for sale at seaside resorts or as parts of various magic sets – were imported directly from Bartl, as well as other German makers.
