HOPF Bass Recorder

This is a Hopf tenor recorder that I received from a friend about 50 years ago.
It is very old, but it produces a very deep sound.
The spring for the right index finger key is firm, but the pad needs to be replaced. The spring for the little finger key needs to be replaced. The pad also needs to be replaced.
The joint of the vocal part and the mouthpiece are firm, but there is rust. (Photo 4) Some decorative parts are chipped. (Photo 3)
There is no case.
We ask that those who understand that this is a used item please purchase it.
I do not smoke and I do not own pets.
