Hello all, hi Lee, what You saw on that film was nearly identical
with the "Mikiphone" that was able to play 30 cm [12-inch]
shellacs. Here are two quick references (there should be others in
English by Googling Mikiphone or "smallest gramophone of the world"):

It's not identical to that used in the film, but you see that it's
possible and no fake to minimize gramophones. Maybe somebody else
may give a better hint to find out for the origin of that instrument
in the film.
