I need your help with some information about a bike I want to buy.
I found a vintage steel bicycle named De Santis, but i don't find any information on internet about such a manufacturer. The bike apparently is equipped with Campagnolo.
Do you know something about such a model, can you tell me some information about its value, or the frame quality ? Someone suggested me that probably was build from a large manufacturer from north of Italy and then branded with the name of a local bike shop.
I will post some pictures ( not good quality) maybe is helpful for you.
I will appreciate very much any information you can give me, because I must decide if it is worth buying the bike.

Thank you,

Mihai
