I went to see a friend's piano... Apparently the instrument is about 170 years old, full-size grand... Unfortunately, I forgot to take photos of the action, but anyway we pulled it out and I looked inside. It has a single lever located below the hammer shank, but it is independent; that is, there is no pin connecting this lever to the hammer shank, but it rests gently against it.
This lever I am talking about has a sort of wide slot on the upper side, from which a small wire emerges and goes into the base... I didn't understand its function...
The hammer shank, on the other hand, is without a roller, and as I was saying, it rests on this lever... What type of action is this? In the Pfeiffer manual (which lists various types of historical actions from different manufacturers), I don't seem to see it... However, I see it as being more similar to a "push" type action... Even if it isn't exactly the same.
From the front side of the key, there are some springs...
I have the impression of playing something very fine and delicate in terms of touch...
Unfortunately, however, everything needs to be redone. I wouldn't want there to have been something else initially on this protruding wire. What do you think?
