As accordeon companies go, Polverini does not enjoy a positive reputation with Euro players.. mos=dest quality.

Known to make for others for rebranding.

Polverini made kits for the 1 row 4 stopper.. they were sold to the public as well as "Mr. John" and others.

Anyone could buy them including Savoy.

They were grossly overpriced in the US at $1000
