Didn't Silvestri also make squeeze boxes?
I was bought a Silvestri (Catania) guitar when I was eleven or twelve - in black, because I was going to be a cowboy when I grew up - but I sold it in my very late teens without learning to play anything at all except the scales. Perhaps if it had been an electric one instead I would now still be able to play the scales, but louder. That would have attracted all the ladies in the El Paso bars! But it sure would have frightened the horses.
