Alfredo Santoni, Fabio Somaini and Luigi Bulgheroni were the principals in the Ditta Giglio (“Lily Company”) in the city of Parè, in the province of Como, in the Lombardy region of Italy.
Most of the available information out there about Santoni and Ditta Giglio is on my blog. If you have any additional information you'd like to share, please drop me a line at firstname.lastname@example.org.
I'm going to categorize these horns after the saxophones they look like: "DA" and "SDA," for the Buffet Dynaction and SuperDynaction (respectively) and R. Malerne instruments. The only name I've found that could be considered a model name is "Mogar."
