Hi; I'm writing from Florence Italy; I'm sorry to bother you but I need help to estimate the manifacture date of one Masi Bicycle if you can. I send you same pictures of it. Can you identify it? Looking at the pictures in Masi register site I got dubs about the fact that this frame is a real Masi. Please can you help me to date this frame and if is possible let me know if his building is original. Thank you very much for your help. Moretti Paolo
