1921 Kurtzmann Glass Phonograph

The 1921 Kurtzmann Glass Phonograph was the hipster audio freak's must-have long before Bang & Olufsen. It played vertical cut discs of the Edison/Pathe variety. But could be modified to play lateral cut gramophone records with the use of an attachment to the tone arm.

And they're still very classy looking.

And in the days before electrical recording, vertical cut discs were sonically best for acoustic recording than conventional lateral cut gramophone records. A suddenly loud passage could cut through the wall of a lateral cut groove, so the singer had to stand back from the recording horn or the horn had to be muffled to protect the groove wall of the record being recorded. On a vertical cut groove, it only makes a deeper groove.

The teak horn inside was perfect for acoustically recorded records, Not brassy or tinnier than it had to be with conventional gramophone horns. Or boxy like Victrolas.  

They're extremely rare today.
