Description

Equipment used for photographing customers' telephone meters. The process of billing customers for their telephone calls was made significantly easier by photographing the meters in batches using a specially-adapted camera. The readings could be transcribed more comfortably in another part of the exchange and a permanent record resulted which was useful evidence in case of dispute.
