Great news !
We have his name !!!
I found this man, the other day in Toh è morta la nonna (1969) as factory manager, since his 3 other colleagues (including Marocco and Alias) were credited , i fought he must be credited too, so i search for the big cast list of the movie, and i found an actor who also seems to be credited in other movies, including UN Amore oggi (1970)
So i checked Un amore oggi, many many thanks to Fauno from Davinotti forum, who search and saw the movie, and our generico is present in the movie as the father of the protagonist
So gentleman let me introduced mr OSVALDO PECCIOLI !
This is a very important discovery, because Osvaldo is everywhere, and im gonna show you
But first his credited role in Toh è morta la nonna (1969)
