This is probably gonna be my last major post about Pino. This is more of a documentation for myself, but I'm trying to deduct Pino's age. So here I go:
Point 1. Drinking Age - 16
There is no drinking age in Italy nor is there a alcohol purchase age. However, to be served alcoholic drinks in public places, an Italian must be 16 years or older.
Point 2. Smoking Age - 16
Pino is seen smoking in the manga several times and it is eluded to in the anime, though no one is seen smoking in the anime. There is no smoking age in Italy, but the minumum purchase age is 16.
Point 3. Age of Majority - 18
Pino is able to live by himself without any kind of supervision. The age of majority (legal adulthood) in Italy is 18.
Point 4. Driving Age - 18
In the manga and anime, Pino drives a Fiat Punto. The age one in Europe can acquire a class B license (a normal car) is 18 years old. It's also eluded to that he has a class C1 license, but that is also for people 18 years of age or older.
Point 5. Gun Law - 18
Italy is known to have the most restrictive gun laws in Europe. There is no right to keep and bear arms in Italy, and the right to possess arms must be obtained via license. Pino owns 3 submachine guns, 3 handguns, 1 sniper riffle, and 1 shotgun along with many knives. The applicant for a license is 18 years old and the applier must demonstrate he is capable to handle and use a firearm safely. However, there is a separate license for carrying a concealed firearm, which is nearly impossible to obtain. Even most policemen are forbidden to carry a handgun. So there is a possibility that Pino has illegaly obtained firearms. He is an assassin, after all.
Point 6. Christiano's (surrogate father) Quote - 18~19
"That 'boy' is a grown man now. His independence is the best thing for him."
So, Pino's probably around the age of 18 or 19. Possibly closer to 19 since the timespan from when he is first introduced until the day he dies is a little more than five months (stated in manga and deducted in anime). If anyone has any other idea that could narrow down his age, let me know.
And last note, I found a funny panel while screencaping:
