Hello to all,
C. A. Ahlstron and his Brothers did indeed make high
quality Pianos.
In addition to their non-blockable action they employed
a self regulating device in the action to insure that there
would be no blocking.
A special feature of their later pianos is the incorporation
of a system of auxiliary or sympathetic strings in the upper
register. Experience and logic would lead us to believe it
was similar to the German " Bluthner " Aliquot feature.
I would appreciate any and all factual information on this
"Ahlstom" feature. I need this info. for the PTG. Museum.
Regards and
Thanks
