The weight of your frame and the features on it don't point to a high end Bianchi. In fact the weight does suggest a budget tubeset and I'd agree with the poster above, probably an outsourced, non factory frame.
That's about the short and tail of it. You might not like the answer, but you can't make an SBDU 753 out of a bog standard 531 Team Rep. However hard you wish it. Same with Bianchis.
