The two-manual pneumatic discharge instrument was built by Emanuel Štěpán Petr in 1903 (Op. 155). This remarkable romantic instrument is housed in a massive organ case and is rarely preserved in its original disposition and masterful intonation.

The instrument was repaired many times during the 20th century (1931 V. Poláček, 1947 Kutná Hora, 1979 J. Hubený from Protivín, 1993 R. Stehlík from Rohatec), but nobody managed to prolong the life of the not very successful design of the die-outs and the complicated coupling apparatus in the playing table. Therefore, the restoration plan chose the option of converting it into an electric tract. The work was undertaken by Ivo Roháč from Olomouc as early as 2005 and the conversion lasted intermittently until 2018.
