A five row accordion

The instrument is one of the oldest known Cooperativa imported by Soitin OY in Vyborg. The body is stamped with the numbers 120 (number of basses) and 322 (serial number). Cooperativa’s own corporate stamp is placed on the treble, but unlike other stamps, this stamp is the size of a small business card and it is having a rambling pattern. The accordion has a sturdy bass sound and the reeds are attached with nails.
