I found this bike on Italian internet sale page. This is beautiful bike Lygie Italia from 50'. The bicycle is in good codition. I was very surprised that nobody bought this bike before me, because it was on sale more than 14 days. Here is some history about Lygie Italia from another internet page: https://utahrandonneur.wordpress.com/lygie-history-and-racing/
For my opinion the stem, handlebar and brake levers are not original.
