Lamj, most Bassos will have the name pantographed into the top of the rear stays and often have their own brand stamped into the dropouts as well. Mine also has 3 small lines cut into the underside of the bb shell that looks kinda like the Adidas stripes.

If it doesn't have any Basso markings at all then it's either at the bottom end of their range or perhaps not actally a Basso.

Thanks both, I hope it does!
