Well, I have this theory, that the serial number is the year and the month. So I would guess yours was made 1959 in August (8). But that is only my personal theory. It has been definetly build before the late 60s since the factory was shot down than sometimes.

Yeah, you are proboably right. But they didn´t build many saxophones at all.
I don´t have another hint. There is no way to get the serial numbers. I don´t understand, why Leblanc/Vito makes such a big deal out of these serial numbers.
