How is possible to buy and own a gun without its serial number?
I'm sure there are millions of guns out there without serial numbers, FWIK really vintage guns were often made without serial numbers, although sometime in the gun life the owner should have taken it to the Police and done all the papers to have is serialized.
The lack of the s/n is often an indicator of a stolen gun here and owning a gun like that would lead you in serious troubles.
