Why is it so hard to find info on Bianchi's?

I don't think it qualifies as vintage, but I figure this is the best place to get info. I just bought this Bianchi Alfana from my LBS for $50. It needed some TLC, but it's good to go now.

Anyway, I haven't been able to find much info about this model. It has a full Shimano RSX group, a 3TTT stem, Ofmega headset, and Ambrosio Super Elite rims on RSX hubs. Please check out the pics and tell me any info you can. I'm wondering what year it is, where it sits as far as quality of the frame, and if these are the original components. An approximate value would be nice, but not nessicary. It has a serial # A404521 on the bb shell and a sticker on the bottom of the dt nex to the bb with 41179589 on it.

Thanks for any info.
