    Ads for this speaker began in March 1923. Ads throughout 1923 from Murdock and Barawick both show the aluminum neck with 'MURDOCK RADIO' marked on the side of it. Beginning January 1924 ads show the aluminum neck with no marking. Murdock appears to have stopped advertising these in magazines in early 1924 although distributors continued advertising them, probably until their stock was depleted.
