The body of the organ is wooden, on the plinth with figured feet, with brass onlays on the side ribs, veneered with mahogany and varnished. Carved foliate golden colour ornament is on the front side. Fourteen wooden piccolo pipes with plugs are in the bottom part of the facade. Inscription in the frame is below "Bacigalupo, = Söhne", "Berlin: N.58", "Schönhauser Allee 74a". Belt brackets are on the lateral sides, pinned barrel removable lid with an aperture for the axis is on the right side, a crank in the form of an anchor that raises and lowers the key frame is on the left side top. Knife and bolt mechanism is below. Two lids with hook locks are on the top panel, the keys with sticks and piccolo pipes are visible under the front lid. A branded blank with a hand-written list of tunes (in German) is on the inner surface of the rear lid. Pinned barrel for seven tunes and a key frame with twenty-five keys according to the number of basic tones are under the lid. With the key frame raised, the barrel can be set in one of seven positions according to the selected melody. Metal crank with wooden handle is on the rear side.

The organ is mounted on metal slats fixed on wooden panel. When the crank is rotated, the worm gear rotates the shaft, and the crank gear activates the working bellows that pump air into the wind chest with the valves. The pins and bridges on the pinned barrel shaft raise the keys that open the valves of the respective pipes; the air from the wind chest enters the wind pipes and makes them sound.

Music media: pinned barrel.
