Classic & Vintage - Help identifying a Bianchi frame

Hey everyone, I've recently purchased an older Bianchi frame "Campione Del Mondo" I believe is the name of the frame as well. On the head tube what I believe is the serial number "4B29370" is printed. I know that Bianchi serial numbers aren't really understood, but does the 4 mean it's likely a 1984? The only original component still on it when I got it was a two part campagnolo pump bracket, if that could help date it. I've posted a couple pictures but could post pictures of any other part if it would help

Thanks a ton!

Can't really help you on year or model, othe than its from the 70s or 80s, but its not a high end Bianchi. The eyelets for the fenders would not have been on the high end racing models, but its a nice frame in good shape. I wouldn't repaint it, the paint is in pretty good condition.

That must be older than 1984. Do the dropouts and fork ends say "campagnolo"?

Also, is the sticker on the down tube (near the head tube) a tubing sticker? What does it say?

Thanks for the quick responses

The dropouts do not say campagnolo

The tubing sticker on the down tube says "Tubi Bianchi Calibrati 1 - 20"

I do like the frame, I'm by no means interested in flipping. Just a nice frame that I'm gonna enjoy

The frame is a Rekord from the mid 70's. It was the low-mid line Bianchi depending on the gruppo. I believe they are straight guage or perhaps butted main tubes and about 7lbs and change for the frame and fork.

It's no Specialissma but still a very nice riding frame, and worth building up with a Nuovo Record gruppo and a nice set of wheels.

Bianchi's from the 70's are pretty rare in the States. With good 70's period parts that would be a really nice and somewhat unique ride.

Here's link to a catalog page showing three versions of this frame built: Rekord 748, Rekord 746, and Rekord 745. You want to build it up like the 748!
