Welcome to the forums.
From the bright and almost unblemished paint paired with the seasoned fork, atypical color and graphics, I think you have a repainted bike.
Many of these bikes were sold to shops as frame sets, so the mixed ensemble of parts is not a big surprise. Sugino cranks were the thin wallet alternative to Campagnolo by many a racer, other parts, who knows.
Maybe a prior owner just did not like Campagnolo.
