DD, really enjoying your Bianchi resto. I had one of similar age a long time ago. Same fork crown, no chrome on the lugs and circled B’s on the seat stays and down tube lug. Mine also came with panto seat post and 3ttt stem.
You may be familiar already, being a fellow Navy man, but that Zumwalts price tag places that bike in San Diego (at least the bars) at some point. The Zumwalts had a shop on University Ave in North Park for many years.
