Please help me identify year and model of my Paolo Soprani

[Bayern]

I have a Paolo Soprani 120 Bass Super Paolo with 15 Couplers on Treble side and 7 Couplers on Bass. I has no identification numbers.
Can anyone tell me what year or model this accordion is.
On the inside the only marks are number 86 or 98 stamped on all parts.
Any help would be much appreciated
Regards Hans

or model this accordion is.

I think this may be a "Super Paolo": the Super Paolo badge and the "SP" grille logo are indicators.
Possibly late 1960s/early 1970s.
It has 5 treble voices, giving an MMM musette coupling.
Nice!
