As far as can be determined, this was the most important of Halbich's organs, and ranked among the largest in Moravia at the time. It had twenty-five
voices, meaning that it was also the largest organ in Olomouc, even exceeding
Agodoni's organ in the Olomouc Cathedral which had only twenty-three voices.
The Krnov (Rieger-Kloss) firm finished the reconstruction of Halbrich's
instrument, and the reconstructed organ was approved, in 1977. And, as the
approval officer stated, the goal had been attained: to restore the original
sound and appearance of Halbich's instrument.
