OK, I finally bought that bike.
I think it says: Milan - Sanremo
and not campione.... (the right traduction would be World champion for campione del mondo)
Anyways, I had a closer look and got more info.
-Shimano dropouts (sounds weird to me)
-The cranks are ofmega (52-42) and six speed in the rear (12-18)
-Alloy rims (tubular)
-Modolo flash brakes and levers
-Campy valentino derailleurs
There are also bunch of shady stickers saying ''Made in Italy''
And another saying ''Distributor Montreal'' If that can be of any clue.
Once again, I'm no expert and I would like to date/identify that bike.
thanks for the input!
