Mr. Yoshiro Kido who owns a BBB (Tres B),
confirmes this behaviour and consideres it tasteful.
The dimensions are close to an ELA instrument.
However, the fret work and other details remembers of an AA.
Mr. Werner Meinel, a former owner of the Meinel & Herold
Company explained that the company's philosophy was always
to sell directly to the customers, at least for the domestic market.
As he confirmed, the offered bandoneons were manufactured by AA, ELA,
and particularly the quadruple reed instruments by Gebr. Meinel,
Klingenthal. In spite of the name of the latter,
they were independent and had nothing to do with each other;
in Klingenthal there are about 400 families with the same name.
After World War II the Meinel & Herold company was nationalized, like all the other companies, and controlled by the VEB Klingenthaler Harmonikawerke. At this time the bandoneon market was already insignificant. During the early 1970s M&H was integrated into the Gebr. Gündel, Klingenthal company and the bandoneon production definitely vanished.
