Hi, I am trying to identify an old Bianchi with Ishiwata Magny tubing. Reading elsewhere on the forum indicates "that it was contract manufactured in Japan but it's not the top Japanese model, the Limited. which used CrMo tubing. However, it's also not the bottom of the line model, the Standard, with hi-tensile tubing." Serial number is BS588389. Says B3 under the bottom bracket - I would guess this is a part number? Can we date the bike - early 80's but which year? Also can we identify the factory of manufacture? Thanks!


1980's Bianchi
