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.
