I think the brake bridge is cast rather than extruded because the legs of the V are airfoil shaped, not flat. Either way, I was just trying to pin down the year the frame was made.
Pics of the entire bike, instead of just the rear brake bridge would be helpful to nail down the year.
Pinarello's can be tough to ID exactly, but some here seem to have an idea.
All I know is Columbus was making IC bridges by 1984 for sure.
