You're right the Canonet has a buttery shutter, it took me 10 rolls to get used to it.
But since your canonet is in excellent shape, don't take too much attention to that minor thing.
My ancestors were Balinese, my grandmother was a Balinese princess (I think there are a lot of them). My father was born in Singaradja. I will sure visit you when I'm in Bali, but that will take some years.
