I came across this recently on the second-hand stand outside a bike/sports shop near where I live these days in a small town northwest of Milan. From what I've read here on the forum, some of the Campag experts may be able to date it for me from the kit fitted to it.
Acting completely on the spur-of-the-moment, I took it away from him for very small money without even riding it, having just taken out the wheels to spin them in my hands and had a fiddle with the cranks for play in the BB.
Briefly, it's a hand-built frame, built by the owner of the shop who used to do that until product liability legislation and insurance costs made it prohibitive. That's his name on the frame. Columbus tubing as identified by the sticker in the photo further down and Camp Chorus everything - almost.
No shoe marks on the cranks, very little wear evident on the chainring teeth, I subsequently changed the saddle, put some LOOK pedals on it and went for a ride during which it all seemd to work quite nicely.
The lad in the in the shop thought it might be 12 or maybe 15 years old but with 8-speed, I figured it might be more than that. Not having been riding for some time and not having enything in the stable younger than my Raleigh Royal tourer from about 1991, I'm not familiar with this stuff any more.
