Clockwork Spirit Bell. Circa 1920. Orange glass bell with nickel-plated hanging hardware is hung from a cane or the magician?s wand. On command, the clapper springs in to action, ringing the bell once for ?yes? and twice for ?no,? in answer to questions posed to the mysterious device by the audience or the performer. Height 5 ??, diameter 4 7/8?. Key-wound clockwork mechanism concealed inside the bell. The first example in this form we have encountered. From the Larson collection. Rare. See Salon de Magie, page 296.
