Hello maestroinpatio and welcome to the forum!
The forum has had other discussion threads on the Bianchi Rekord 745. You can use the forum's search function to bring them up. To know how kitted one would need to know a model year; they kept evolving.
The unmarked frame ends on the subject frameset are likely Agrati "CORSA RACING." Frame constructed with Agrati bulge-formed head "AM" serie nr. 000.8046 and Agrati seat lug serie "EXPORT."
