      HI.
      I found Martin's Vibroplex ad on March 1905 issue of "The Railroad Telegrapher", suppl. 16.
      That ad is from O.T. Anderson of Chicago, IL, a typewriters and morse keys vendor. It talks about a "new mechanical sending machine - the Martin Vibroplex, Price 12.00 USD".....
       
      It is 3 months before the "The Commercial Telegraphers’ Journal", June 1905, Pg. 32, first official announce according to WW7P's list (http://www.la.ca.us/frandy/dating.html ).
