Hamburg Steinway, sostenuto - not

[Joseph Garrett]

Allen asked: "I'm rebuilding the action and restringing on a 1926 Hamburg Steinway 
O 170, and was surprised to find that it has no sostenuto mechanism, 
although it does have tabs on the damper levers (the old un-hinged 
kind). It's not just missing the mechanism - there are only two 
pedals. This is my first experience with an old Hamburg; I wondered 
if others with more experience with them (Europeans perhaps) can tell 
me whether this is typical, and when they started installing 
sostenutos. Perhaps other models had the sostenuto in this era, and 
that's why these dampers have the tabs?"

Sincerely,

Allen,
The Sostenuto mechanism was invented by Steinway in the mid 1870's
