A customer of mine sold me a 12 guage over and under italian shotgun. I have no clue what its worth or what exactly the gun is. The only infrormation on the gun is on the barrel and it reads, A1 TAVANA-GARDONE V.T.=MADE IN ITALY. The other side says, ACC1A10 SPECIAL. If you pull the wood stock off it has writing that says, CANNE CHROMATE. Can anyone tell me the worth of this shotgun? Thank you.
