This is a colour changing trick. The magician shows a red handkerchief and pushes it into an empty green tube, which is next wrapped in newspaper. The magician then reaches into the covered tube and removes the handkerchief, which is now green. The tube is removed from the newspaper and now it has turned red. The red tube can again be shown to be empty. The inside of the metal tube is stamped with a Davenports demon head.

The magician fashions a cone out of newspaper and pours some of the milk from the bottle into the cone. The newspaper can then be screwed up and thrown into the audience – the milk has vanished. The words moulded into the bottle are ‘UNIVERSAL MILK BOTTLE NEW OXFORD DAIRY IMPORTED’. The Davenport demon with the words ‘DEMON SERIES’ is also moulded into the glass. A close-up photograph of the moulded demon is illustrated. This trick is not for the magician that likes to travel light – the bottle weighs 1.5kg.

The magician challenges the audience to spot the cup under which the cork is hidden. At the finish the magician lifts a cup and produces from underneath it a large cork which fills the cup. The cups are stamped DEMON. Unfortunately the stand which was sold with the trick is missing.

The magician shows a copper coin – an old English penny – and covers it with a handkerchief, saying that it will change into a sovereign. The audience expects to see a gold sovereign coin, but on the removal of the handkerchief there is a statue of the Sovereign, King George VI. The statue is marked DEMON.

The magician asks a spectator to mark a coin so that it can be recognised again. The coin is vanished (by your favourite method!) and is found trapped inside these two plates which are bound together with numerous rubber bands. A Davenport demon head is embossed on the front of each cover.

A nest of four bakelite boxes, the outer one of which is decorated with a Davenport demon head trademark. The magician vanishes a coin and then it is found in the inner of the four boxes.

This trick was invented by Brian MacCarthy. The performer is able to mysteriously pass a playing card through this wand. The wand is stamped DEMON on one of the white ends.

This nickel plated box is shown empty and then a number of handkerchiefs are produced from it. This was a very popular trick first marketed by Davenports in 1934. The inside lid of the box is stamped with the Davenports demon head logo and the registered design number: 791997. Davenports purchased the UK rights from Janos Bartl in Germany, who invented the trick. Bartl sold the trick under the name ‘Silkwonder’. The screws on the corners of this model have non-rounded heads. Some models – for example see N46 – have rounded screw heads. Note that the stamp inside the lid differs from that of N46.
