Help finding out my vintage Biachi model

[Ollieno12]

Hi guys,

New here. I bought a vintage Bianchi road bike like 4 years ago. I have barely used it as I now live in the US.

The bike had been completely refurbished and looked like new. Unfortunately the owner passed away and his mother was selling it.

There is a number on the head tube which is 701848.

Can anyone help me with what Bianchi this is?

Thanks
