The accordion has a text ‘Stradella’, even though the instrument is German made. Stradella was often emphasized in Finnish accordion brochures in the 1920s, for example by mentioning Stradella corners. Stradella accordions have thus been considered an example and a style direction. The accordion in question can be found e.g. From the brochure of R.E. Westerlund Oy (ltd.) from 1922.
