The organ is mounted in rectangular vertical case made from pressed metal and painted with red enamel. The upper parts of front and rear sides are fixed by latches and might be opened. 43 polished metal goldish color flue organ pipes are on the upper side. Piano-type keyboard with forty-three keys, closed with metal cover is in front of the pipes. Folding carrying handles finished with polished goldish rims are on the lateral sides. The nameplates with the model name, operating pressure and form- manufacturer are on both sides between the handles. Air-pressure indicator with circular scale graduated in force-per-square-inches (psi) designed to measure air pressure in the system. Air-driven organ control system is mounted inside the case. It allows playing melodies manually on the keyboard, and play musical pieces recorded on paper music rolls. Coiled round the spool paper music roll is drawn along the track bar with apertures. When the apertures in the paper music roll and the track bar match, air enters the system and opens the valve of the corresponding organ pipe, into which air is pumped under the pressure, making the pipe sound. The paper music roll movement is provided by electric drive. External compressor generates the air pressure in the system. Special flue pipes with ring-shaped flue slit are used in organs of this type. Air stream from sich pipes breaks against the lower edge of the cylindrical resonator lower edge. The sound emitted by such organs is audible for many hundreds of meters.
