That is a rather significant but subtle identifier, IMO. Most definitely this information will be helpful to others. My 98' Nth has that stamping as well. Can't fake that on a cheaper frame without butchering the bottom bracket housing, I'd bet. Reviewing the eBay post above, the seller knowingly or not, doesn't show the non-drive side of the bike.Anyone wanting a nice Bianchi Nth or similar from the 90ies has to be careful and do their research. Otherwise they might blow money on something mass produced and not worth much
Genuine hand built Reparto Corse race frames were built with top end tubing such as Genius or Zero and had the Bianchi text cast on the bottom bracket shell.
