This Seymour Superphone is the only known survivor. A very special thank you to David Evans for the pictures.
It was designed and built by Henry Seymour. It was the culmination of many years of experimenting and by 1916, it was considered the best gramophone available. This is the model that inspired Michael Ginn and David Phillips to make the Magnaphone, which is basically the Superphone in an internal horn cabinet. The Ebonite horn, tonearm and soundbox were made and sold by Henry Seymour.
The ‘Seymour Sound Box’ box and pictured soundbox are with the machine. The pictured ‘Superphone Soundbox’ box was found recently minus it’s soundbox with no clues as to if it is any different from the one shown.
Note the mysterious metal peg just behing the turntable. What is it?
