When did pinarello quite making "traditional" style cromo bikes?

I have a Pinarello, quite old, but I don't know when it was made. My friend said it was one of hte last of that type. It has the stright tubes in a trianble shape, like road bikes did in the 1900s. I don't know if Pinarello continued to make that style into the 2000s.

I've lost the bike in a fire. The frame is warped and everything else melted. I need to tell the insurance company how old it is. If I can figure out when they quite making these, and can believe my friend who I bought it from, then I can guestimate the age.

Thanks for any help!
