I knew Sonny in my youth in Summit, New Jersey. Close friends with him and two of his three sisters: Moira and Evadne. We spent a fall together flying motorized model airplanes on the weekends. Sonny would bore and stroke their engines and we would fuel them with the methanol he used to propel his (garaged) racing bikes. Before that, his siblings and my brother and I would get together for endless games of Monopoly (I remember Moira crying) and caroling at Christmas in Countryside where the Gianninis lived (my family had lived there, too). Have not seen them for more than 50 years. How our lives fly by...
So sad to hear of Frank's passing. I knew him for a number of years; and he rebuilt the motor on one of my race bikes. I moved out west in 2018; so lost touch with all the east coast people into vintage racing.
He was a unique and very talentred man. I'm glad to have known him.
Condolences to knew him.
