Paavo Raivonen played an accordion like the one in the picture in the Dallapé Orchestra in 1932–34 and also recorded with it in Berlin and London during that time. The instrument has exceptionally loud and clear sound. Bass reed plates are wedge-shaped large plates that thicken from the rivet tip to the tip of the reed.
The serial number is 139.
The accordion has been imported to Finland by Soitin Oy. The instrument is coated with white cellulose acetate, which is insoluble in acetone at all. Its advantage can be seen over the years – the surface does not turn yellow. The other colors in this Cooperativa are celluloid.
