one of these is reported to have been commissioned by author ian fleming "after finishing the first draft of casino royale, ian fleming rewarded himself with a royal quiet deluxe portable gold-plated typewriter, which he used to write the rest of his books and short stories. fleming bought the gold-plated royal quiet deluxe portable typewriter from a new york dealer in 1952". according to the guinness book of world records, this typewriter is the world's most expensive: "ian fleming's gold plated typewriter, which was commissioned by the james bond writer in 1952, was sold for £56,250 ($90,309) at christie's, london, uk on 5 may 1995." author ernest hemingway also used a quiet de luxe. "a manual royal typewriter that once belonged to ernest hemingway, made around 1940 and still in its well-worn leather carrying case, sold for $2,750 at a multi-estate sale held june 24th [2007] by four seasons auction gallery" in atlanta, georgia, although it is not clear whether this typewriter was a quiet de luxe or the very-similar arrow model that hemingway also used.
