Hi again everyone! i took a look all over the bike and i just found this number: 50027. I look on the internet but found nothing...
I also took off the mudcaps to make it lighter and bought a new saddle, it is a san marco bianchi model in celeste, it will harmonize with the bike i think.

what do you think about the serial number?

Ah! and the sticker of the store it was bought. it says "Del Castillo" cycles mecanicien

Thanks in advance
