Shimano produced New 600EX for the 1984-1987 models. When introduced, they retained the BL-6300 aero brake lever from 600AX has an aero option for New 600EX. The dedicated BL-6209 aero brake lever wasn't introduced until the 1987 model year. I can't identify the brake levers from the photograph but they're definitely not OEM, as the 1985 Bianchi Limited was spec'd with the standard BL-6207 brake levers with external cable routing. Aero brake levers became one of the most popular upgrade in the late 1980s, so it's not suprising to find them on the subject bicycle.
