This talking clock was manufactured in Berlin by B. Hiller at 300 examples (according to V. K. Chew), even if this one has "407" as serial number.  The 48 recordings (12 hours, quarters, halfs and three-quarters of an hour were on 48 tracks of a celluliod ribbon of one meter long (39").  This belt can be easyly associated to a cylinder of 31.8 centimeters in diameter (12").  Like the ordinary cylinders, the recording is a vertical one.  It is played by a saphir reproducer of the same type than the ones found in Europe on highandale disc machines as Pathe.  The spiral part seen on the right of the horn pushes the reproducer of one track each 15 minutes.  Most of the time, the recorded belt is broken (when found) due to the fact that the tension of the ribbon is not made by springs, but by a screwed tension roll ajusted by hand.   Unfortunatly, celluloid, containing camphor has the tentency to shrink with time as soon as the camphor starts to slightly evaporate.
