It's an "old style" Marine Band that they manufactured as a souvenier of their 130th anniversary, and plays much the same - it was intended as a "reproduction" of a model from the 1920's, when they were putting out as many as 15 or 20 variant cover plates on the thing - the guts were the same - as are those of the repro. Hope this helps. Steve Jennings, Editor, Harmonica World
