Deutsche Konzertina
Chemnitzer System: Uhlig, 40 tones
bisonoric, logical
(Collection Oriwohl, Nr. IV-36) ♫ Audio (only demo, no art)
Manufacture: presumably around 1850
Another of the early concertina models with 40 tones. In contrast to all other concertinas, the manuals are rarely attached to the front.
This arrangement on beveled front surfaces is not known from any other model. Only about 150 years later, it is reappearing on the unisonoric Hybridbandonion.
The instrument in playing disposition.
Demonstrated by collector Karl Oriwohl.

The tone assignment of both manuals corresponds to the graphics of the previous instrument, but with C and F major.
Mechanisms made of metal, as can also be found in principle in today's hybrid bandonion.
The vertical key operates the air flap of the bellows.
The white, round closures are lifted by the linkage and so they let wind through to the respective reed.
The reverse side shows two collective reedplates with riveted reeds on flat chamber.
On the far right is the air flap, through which the bellows can be filled or emptied without sounding a tone.
