There's a thread from 2002 in the MMD archives about barrel organs made
in Odessa by Nechada:  http://www.mmdigest.com/Pictures/nechada.html 
This shows a 26-key barrel organ and notes they were widely used in
Tblisi, Georgia (the country, not the American state).

This seemed rather familiar, and indeed turns out to be very similar
to the crank organ in the short film "Hakob Hovnatanyan" from 1967,
directed by the renowned Sergei Paradjanov and made in Armenia (just
across the mountains from Georgia).  Talking with Robbie, it seems
that the one on the film is larger than the one discussed on MMD, but
otherwise is very similar in case design and decoration, and (now I
know) can clearly be seen to carry Nechada's name as well as "Odessa".

What's most interesting is the music that it plays.  It's a long way
from the sound that you might expect from its Black Forest progenitor,
showing how much these instruments evolved for their setting.  Even
better, you can hear this for yourself thanks to YouTube, which has
a 2-minute clip showing the organ being played followed by scenes with
music from a similar but different instrument.  The first piece is
a very eastern European piece in duple time, and the second is a waltz
of some form.

I'd love to know more about them if anybody can do better at identifying
them!  Have a look at the clip while it's there, it's well worth it.
