Although it would appear that the Reflectograph was moderately successful during the mid 1950s, Rudman Darlington decided to dispose of its interests in the the business and in early 1958, all development and production passed to a newly formed company Multimusic Ltd, Hemel Hempstead. This company was a subsidiary of Multicore Solders Ltd and was formed to handle their magnetic tape accessories such as the "Bib" splicer which had been invented by Richard Arbib, who was to later become their managing director. As for Rudman Darlington, it would appear they carried on with their original business of can openers and appear to have survived into the mid 1960s. What little records survive at Companies House, London suggest the firm was dissolved in April 1968. Unfortunately very little else if anything survives from the Rudman Darlington days, so I would welcome any further history and insight into the company.

Dr James Cunningham Sands moved to Multimusic, becoming their technical manager at Hemel Hempstead. Production of the existing range continued with the Reflectograph Models 500, 501 and 400 series. The 500 was now available in "two tone" luxan hide and pigskin coloured Rexene. Two specialist Reflectograph continuous music decks were also advertised under Multimusic and known as the Model 81 and Model 90 Series. It is assumed these were also carried over as part of the buyout. These particular decks appear to have disappeared shortly afterwards.

By 1959, two further models, the 500 and 570 had appeared on the market, Mono and stereo respectively. These appear to have faired better in terms of sales and examples of these turn up from time to time. It would certainly appear that Multimusic gave the recorder plenty of advertising and the reviews of the 500 series were very favourable and deservedly so.
