Hupfeld Phonoliszt-Violina with ROLL SWITCHER at Siegfried's Mechanisches Musikkabinett

This here is one of the very few if not only existing videos of the Hupfeld Phonoliszt-Violina with the dual roll switcher. The instrument holds two rolls at a time and can easily switch between them faster than any other automatic roll switcher ever made. You will notice that the roll in the front is actually not the one playing, that is because the tracker bar is located all the way in the back and the roll facing away from the front is pushed against it.
To my knowledge, there are no other examples of this left in the world other than this one at Siegfried's Mechanisches Musikkabinett. I tried to get as many close up shots of the mechanism as I could during the video and I hope some more videos of this instrument will be popping up on KZbin soon. Enjoy! :)

Great video! This instrument is sometimes on loan in other museums and there are other, partly professional, videos of it. I find it more interesting that this museum has a rare "Violina-Phonolist" on display. It is a kind of early prototype by Hupfeld and the only one of its kind from 1909 that still exists. I have already taken photos of it from all sides but I don't think it is in a very good playable condition because as far as I know there is no film footage of it playing.

I got a video of it playing when I was there. It's not a whole song, but it still works! Just needs to be tuned.
