L1 lip microphone, manufactured by Marconi's Wireless Telegraph Company Limited for the BBC, Chelmsford, Essex, England, 1937-1960.

A development of the Marconi ‘B Type’ microphone, the ‘L1’ microphones was designed for use at large events, such as during sports outside broadcasts, where the voice of the user needed to carry over crowd sounds and other background noise. The L1 was designed in 1937. A guard ring that the commentator held to their face ensured that the microphone sat at a consistent 2.25 inches from the user's mouth.
