SparkMuseum displays the collection of vintage radio and scientific apparatus of John Jenkins. Early wireless, radio, scientific and other electrical items up to about 1920 (including books and other publications). His collection of 1910’s and 1920’s horn Loudspeakers is beautiful. The site is a kind of delightful walk through physics history of XIX and beginning of XX century with pictures of pretty inventions. (via All about nothing)
