I have several thousands of sheets of accordion music including manuals, photos etc etc. and likely have multiple copies of most of Magnante's and Deiro's works and many of Frosini's as well and many others. Have old-timer pioneers like Deiro,, Sedlon, Magnante, Gaviani, Biviano, Palmer-Hughes etc manuals. Other lesser known artists like Leon Sachs too.
In the 40's- 60's accordion studios in the Ontario area were involved in many competitions (especially Kiwanis) and concerts and the selections were for that purpose and of course multiple copies were sold to students. And of course we also had accordion bands competing at several age levels.. by the way, still have some of that music too.. To give you some idea of popularity, one school in Hamilton had over 300 students of all ages!!
If you check previous threads, you'll read some of my background, including having a brief unofficial stint with my idol Magnante.
Also performed with other Excelsior artists including Carrozza, Desiderio - both students of Deiro incidentally and Eugene Ettore..
Played Magnante's arrangement of Mendellsohn's Andante and Rondo Capriccioso to win the Canadian championship back in '54.. Yes--70 years ago this June.. Also Frosini's D minor for the '52 championship. Charlie Nunzio was adjudicator.
Music was saved from the 2 largest studios in the Hamilton/Toronto area when they went dark...
Retired of course.. Not in the business but willing to send the original copies for postage and whatever you think may be fair.
(Am also a Rotarian...just to reinforce credibility...)
