The ML-15 ribbon mic.
Welcome to Moscow.
This is the U.S.S.R. version of the RCA 44-BX. It is the Soviet Government Issue (CCCP) Model ML-15, manufactured by the Popov Institute of Radio and Acoustics, and is dated 1957. There were fewer than 500 of these manufactured, and were allowed to be used only for the highest official Soviet government functions and propaganda programming and recording. When Mr. Khrushchev agreed to do the CBS-TV broadcast in June of that year, his people insisted that CBS include these mics on the table, as you will see below.
