Lid open with dynamo handle shown in "stored" position.

Battery storage compartment & battery box in place. This seems to be often missing in these phones. Crank detail at right.

Detail of extra earphone plug connected to phone. At right, the front sockets to allow two phones to be joined together. This is not used to connect the phone to a switchboard.
