I have no proof it is a tange Prestige frame that is just what the Ebay add said
He also stated the frame weghs 2350 gramms but I have not had a chance to weigh it yet.
The welds are all very nice and the seat clamp is also nice.
I have checked the Ritchey catalogues for 94/95 and nothing similar to this and the serial number looks nothing like a ritchey serial number according to the internet.
The serial number on this frame is :
Serrial Number : BN9412970
Does anyone reconize the serial number?
It certainly isn't a Ritchey, but there are several signs that it's a decent quality frame, such as the ring-reinforced head tube, the reinforced seat collar and the cable guide - and I suppose the fact that somebody thought it worthy of fitting an XT front mech.
I can't see anything either way to back up or deny the suggestion that it is made of Tange Prestige, but the weight of 2.3kg tends to suggest not, as it's quite high for a medium size heat-treated frame.
The serial number is in a Taiwan format and I would agree it suggests a build date of January 1994, but I don't know which builder is/was BN.
