Koralion (Transponier-Harmonista)
This is the transponier-harmonista, which can be placed on the keyboard of a normal
reed organ.
This type has 3 rows of buttons, with a total of 28 buttons. This device has been sold in
The Netherlands, we think around 1920-1930. There were special musicbooks for this device
(some displayed at the bottom of this page)
More information in the article in the ROSB.

The name of the device is "Koralion". I found it only on devices in The Netherlands, not in Germany or Switzerland. There I saw only the name "Transponier-Harmonista" on these devices. |

Seen from above. Some buttons are lost, so the device need some repair. |
