Hi,  First of all, if you could take a picture of the musical box
mechanism it would help.

A large percentage of the musical clocks were made by Rzebitschek, and
his name is always stamped on the comb of the musical box.  Two other
interesting features of Rzebitschek are the large gear ratio, which makes
the cylinder turn very slowly, and the fact that the bass or longer
teeth are on the left side of the comb, as compared with Swiss makers
that put the bass teeth on the right.

Please remember that, if the mechanism is not marked, 99% of the time
you will not be able to solve the puzzle that you have presented of who
has made a musical movement.  Not only do they all look alike, but the
most of the makers also would also use the same foundry to make their
combs (raw material), bedplates, spring barrels and other parts of the
mechanism.  The maker's magic was in the musical arrangements, the
tempering of the comb (volume and tone) and the tuning of comb.
