Not sure about older models and can not check ebay from work, the IT folks have blocked that site. The newer ones are only available in 170cm and 175cm.
Some ebayers haven't a clue and are some are down right suspicious. Jim Cunningham pointed one out the other day that was selling a anniversary model Colnago. That same person has a wooden bike up for auction that is kind of cool looking, but it make you wonder if they really have that one at all.
