After doing quite a bit of wrenching for our church bike ministry this weekend, they had a few bikes that were too far gone to be flipped. I made a donation for a few. After loading up a couple of beat-up Schwinns and a Fuji, I picked up this "Cortina" that was made in Italy. It says made in Italy in at least three places on the tubes and the stem says "Italy". I know nothing about this brand except I doubt it is related to the current Cortina brand manufactured in Mexico.

The rear DR is a Campagnolo Valentino Extra, the front dr mount is Campy with a Simplex derailer. The stem just says Italy, but looks like the french Stem of Death. The downtube cable guides are Campy as are the shifters. The skewers are Gnutti, the brakes Balillo center pull. The hooded levers are no-name. The bars are beautiful triple T. The rims are Ambrosio made in Italy, 27". The 5 speed freewheel is a TOC made in Holland. The top bar cable guides are REG. The cranks are no name but are interesting because they are cottered, but only on one side.
While it's not a light bike, considering it's age, it's not heavy. I guesstimate around 28lbs. The paint condition of the frame is awful.
So what have I got? A rare valuable find? An OK pre-bike boom frame with nice components for that time period? Save the bars, the rest is recyclable steel? I have no clue. Any help here is really appriciated as I'm trying to figure out what to do with this. Is this a valuable bike, or just another old clunker with some nice name components?
If you can provide any information, please do so.
Thanks
