GEORG HASCHKA, VIENNA, 1815
Our current work at progress is a Georg Haschka, Vienna 1815. The instrument used to belong to the Colt Collection (UK), and was bought by the Geelvinck Museum (NL) in 2018.
The piano has various major problems, among which the pinblock. It is warped, eaten by woodworm and has to come out. This has to be extremely carefully done to prevent damage of the decorative outer painting.
First step in the restoration process is to take the strings off and to carefully measure and record string lengths and string thicknesses.
