Ethovisor Mirror-Drum Receiver
This is not merely a Television Projector, it is complete equipment, built into a neat Cabinet with the receivers in the base, and all controls are easily accessible whilst operations are on.
Exceptional care and attention have been given to the synchronising gear and associated circuits.
An important feature is the Sound Receiver can be used independently when not receiving television.
