Hi there to all of you, this is my first post!

I was riding near my city and I found a guy on a good looking road bike. I asked about it and he said it was an italian bike named Fanini. I was looking through Internet and I have found here (Example 1, Example 2) some post that mention that (probably) the real brand is Alan.

Can you guys help me with this? Is this a real Alan? Can you tell me the aprox. year of build? The components says Shimano, do you guys know if this brand came from factory with the bike? What do I have to keep in mind if I decide to buy it? Is USD $300 a good value?

I let some pics and thank you very much in advance for your help.
