harpmaker, thanks for this thread. I decided to go look on google to see if there were any sites for busking organ grinders and I found out all kinds of information about hand crank organs in general. Fascinating and amazing; there are even some which use tiny discs, instead of rolls, yet you can still hand crank them and control a few of the elements!

Do all of these types of organs use rolls of music, like the old music boxes? Are any of them like a hurdy-gurdy in that you can, theoretically, play tunes on it; I mean without using a roll?

Thanks, again,
