Sony ECM 16 Lavalier Microphone

This is a NOS piece that does not appear to have ever been used.   At some point an XLR connector was attached and even that is of the old cannon variety and in New condition.

These mics run on S-76 or 675 type batteries.   This piece has been tested and works perfectly.
