1206 HANDBOOK OF PROJECTION FOR The cabinet contains record compartments, one on each side. One of them is shown in open position in Fig. 437.

In this figure we have a view of Motio-Tone 2-disc cabinet, one of the record storage compartments being open.

In fact, it was and is the purpose of this manufacturer to supply a non-synchronous device which might readily be used for synchronous sound reproduction and projection if desired.
