Idillio Del Col was a factory trained accordion technician who emigrated to the US from Italy as a young man. He settled in Louis Park, Minnesota where he became well known as an accordion technician. He imported partly built accordions from Brandoni, completed the work on them and sold them as Del Col instruments. He was also a very experienced player of the 5 row Chromatic System, performing extensively well into his 80s. When he began to struggle with bigger accordions he had Brandoni make him a very compact 2 voice 60 bass accordion that has 2 sets of treble reeds, MM & LM. I'm pleased to now be the owner of this accordion (photo attached) that also features in my Accordionists Forum photo.
