PRIVAT-EAR
This is the original building that Electronics Systems Corp traded out of in 1949. It is located at 112 West 18th Street Kansas City and this is how it appears in modern times. This building was built in 1928 and it was previously used by Disney Studios as a distribution center. 

 

When the company changed its name to Privat-Ear Corp they moved to this New York address located at 2016 Bronxdale Avenue. In 1953 a business called 'Radio Merchandise Sales Inc' also traded out of it.
