Chamber organ in wooden case, veneered and varnished, on a pedestal, on four supports. A hinged lid is on the top panel,  sticker with a handwritten list of melodies on three pinned wooden barrels in English is on its inner side. A removable panel with a lock and oval window with decorative pipes is on the front panel. The pipes are covered with fabric, with the slats on both sides. Semicircular sticker with the image of a lion and a unicorn and the inscription ‘PATENT’ is under the panel, six pull-out handles for register slides and percussion instruments - a drum and a triangle with explanatory inscriptions. Pinned wooden barrel with ten encoded tunes is mounted inside the case, wooden key frame brass overlay and twenty-five sensitive levers, corresponding to the number of basic tones, a set of fifty metal and twenty-nine wooden pipes combined into four registers, a bellows’ system, and a drum with two beaters and a triangle with two hammers are above the barrel.

When the handle is turned, the barrel rotates and the working bellows are set in motion, forcing air into the wind chest with valves that distribute the compressed air between the pipes. The pins and brackets of the barrel lift the reading levers, which open the valves of the corresponding pipes, and air from the wind chest enters the pipes and causes them to sound. Certain levers located on the right side of the barrel control the hammers and mallets via wire rods. The set is comprised of four barrels, a crank and a key.
