All 148 vintage radios were made of Catalin in art deco style
Auctioneers said a collection of rare plastic radios and other mechanical memorabilia "exceeded expectations" when they fetched a total of £207,648.
A rare Harpe Harmonique-Piccolo Zither cylindrical music box, one of the highlights of the London auction, went for a £26,400.
The 148 radios, made between 1930 and 1950, left enthusiasts "buzzing with interest", auction house Bonhams said.
A 19th century microscope and telescope were also popular at the auction.
Art deco designs
Among the popular items were a 19th Century monocular microscope, which sold for £8,160, and a Gregorian reflecting telescope, which fetched £3,240, - more than three-times its estimated price.
The vintage radios from around the world were made using Catalin, a type of resin allowing designers to create objects in the art deco style.
Production of Catalin declined in the post-war period as improved versions of modern plastics were developed.
The collection went under the hammer as part of Bonhams Mechanical, Music and Scientific Instruments.
Bonhams said 91% of the items on auction were sold at the auction on Tuesday.
