Unique Cylinder-Played Music Box Piano

It's a piece of furniture in the so-called "historicism" style (between 1870 and 1890).  It's a very well-manufactured table, 94 x 51 x 78 cm (breadth x depth x height).  Inside this table there is hidden a hand-cranked cylinder-driven piano with chromatic scale, 2-1/2 octaves, 18 notes from g to c, each note double stringed.  It plays 12 different melodies.

The table has a shellac finish.  There is no signature on or inside the instrument.  The only information, inside the table, says "Patent No. 2239".

I did some research with the German patent authorities concerning this patent number and it turned out that this patent was filed definitely before 1877 (when the first all-German patent law took effect).  Before 1877 the patents were not centralized, and were filed in the different German states and districts.  To get original information about these patents one has to know in which state (or better, the district or town) the patent was filed.

From the overall impression and concerning the automatic music patent information, I guess that the instrument was built around 1880, maybe in Germany -- Thuringia (Thueringen) or Saxonia (Sachsen) -- or close to the German border in Bohemia.

I sent some pictures to the editor, showing the instrument and some details of it.  I would be happy to get any piece of information which could help me to identify the instrument more precisely.  If necessary I could provide more pictures.

Thank you for your help!
