"Variations on Slavic Gospel Song" - on Sonola SS20 accordion 

Multumesc mult pentru comentariile tale incurajatoare Daniel. Bunul Dumnezeu cu siguranță m-a binecuvântat mult mai mult decât merit.

Thank you Aslan! I think the different grill fronts represent different models of Sonola accordions. This SS20 is the 'top of the line' model' but there are lesser models like the SS 15 & SS 10. I once played on an SS10 which did not sound that good because it had no tone chamber.
