Who can tell me something about a P28 A. Ruth & Sohn barrel organ?

 [ Willkommen an MMD, Joe!  The book, "Waldkircher Dreh- und Jahrmarkt-
 [ Orgeln," by Herbert Juettemann, says about the Modell 28 Ruth organ:
 [ "Modell 28 : 54 keys, 5 registers, cylinder with 64 measure bars;
 [ plays 9 pieces".  Is this your organ?  A similar organ exists in
 [ Elztalmuseum, Waldkirch.  -- Robbie
