Wooden pipes are tuned with these “stoppers” inserted on top of every pipe. Old leather has disintegrated and had to be removed. New packing was precisely glued on in order to tune the pipes again.

Old pipes after thorough cleaning and repairs. All windchests and pipe support boards were cleaned as well.

Old bellows were damaged beyond reasonable repair – the air was escaping through countless holes and cracks, making a lot of noise and creating an unstable wind pressure. Two brand new reservoir bellows were built and installed in place of the old ones.

Sad picture - an old wooden pipe with the tuning stopper “fixed” with …toilet paper! Unfortunately most wooden pipes looked like this one.

Many metal pipes have been squeezed and deformed by previous renovators. All pipes were brought back to their original round shape and placed in their original locations.

Literally every part of the organ interior was covered with a thick layer of dust accumulated over many, many years. All parts and all pipes were cleaned and restored to a mint condition.

Literally all air conduits that supply air to the organ pipes were replaced with new wind trunks.

This is one of the façade playing pipes. On the right side of the pipe’s mouth a metal “ear” is missing. Its presence is paramount for proper sound stabilization. Many defects like this one were repaired, bringing the entire instrument to a perfect mechanical and tonal condition.
