I believe that version of Superbe Pro came out in 1983 or 1984 and it's not AccuShift, so it should be pre 1987. This was also the period when dual bottle bosses started becoming popular, though I'd also expect cabling under the BB shell. The Superbe FD is the previous generation. It's tempting to say 1985 but I'd check the the coding on the fork's steerer tube per the previous post. Given the era and level, I doubt it's Taiwanese.
