The frame is wooden, reinforced with 4 steel plate bars. The Irish-type dampers are set on wooden plates. There are 2 pedals mounted in a “lyre”. The case is veneered with rosewood. Spruce wood of the sound board is experimentally sawed up: the layers of the part, over which the strings from A of the double contra octave to c of the two-line octave are stretched, are perpendicular to the strings, and the layers of the remaining part are parallel to the strings.
The grand piano was in the Justice School in the period when P. I. Chaikovskiy (1840–1893) and A. N. Serov (1820–1871) were studying there.
