2003 is the model not the year. I have one like it, an over and under, and I think that it was made late 70s (maybe even till early 80s). Franchi remained a family business till 1987 and was then sold and changed ownership again afterwards. It is a fine shotgun, unfortunately fixed chokes, but very nicely made with super smooth action.
See if the manufacturer has a web site with a customer service contact number or email. Try e-gunparts.com, local gun shows, gun shops, etc..
