Serial number help?

[jerneedog]

I just recently purchased a Benelli Nova pump 12 gauge and I'm trying to fill out the warrenty card and I'm having trouble with figuring out the serial number. The box the gun came in has this sticker with the gun's info on it...the left side says "Caracassa" and the right side says "Canna", the dealer wrote on my receipt the gun's serial number that is under "Caracassa" but that's not the numbers stamped onto the gun's barrel (that number is underneath the gun). The numbers stamped on the barrel are the numbers under "Canna". Under the bar codes on both halves of the info sticker, are "Matricola: (serial number that the dealer wrote) and "Matricola: (the numbers that are stamped onto the barrel).

I'm confused as to which is the serial number and what the other number is for.

I also need to know where to find the model number.

Thanks in advance for any help in this matter.
