Went to view a Bianchi - "an original made in Italy". Anyway, here is the SN for your Asian serial number collection.
Serial of H1C5037. Has a made in Tiawan sticker on head tube.
Equipped with Shimano 300EX (seat post replaced and wheel set now mismatched)
Assuming Hodaka made but SN seems to be short a few digits. In the SN photo it looks like there are other numbers stamped but painted over
Sorry for photos, garage not well lit.
It's a 1991 Bianchi Premio, manufactured by Hodaka of Taiwan in March of that year. It was the bottom model in Bianchi's six model, road line. MSRP was $420 CDN. Thxs for posting.
