Hi, I would like to know your opinion on a few matters:

the hammers of old German pianos are not felted because this creates a fuller and sweeter sound typical of the period. Is that true?
the keyboard lid makes a bit of noise, it tends to get stuck when trying to close it. How can this be resolved?

one damper is a bit lazy (chord 30), it descends more slowly compared to the other dampers. How can this be resolved?

Thank you

Denis

Hammers with felt underneath or not are not the same thing.

The lid has swollen. Try some "dry" teflon spray

The sluggishness of the damper depends on the "lazy" pin of its trunnion
