Early Telephone Apparatus
Description:
In 1877 Bell designed the first set with a combined receiver an transmitter that could be held in on hand. It was made of wood and resembled a dairy butterstamp, hence its name. It was in service when the world's first commercial switchboard opened in New Haven in 1878. The pushbutton was used to signal the operator. Reproduction by John Infurna.
