OLDYELLR

Well, I just updated the Nishikis in my sig based on this info. I had previously made them a year newer based on component dates and a poor memory. (The Claud is dated from the serial number and the Jeunet dated by the saddle for lack of any other stampings.)

Edit: Interestingly, my Ultimate has a U.S. serial number, even though it was sold in Canada. These bikes were not in any catalogue and only a small handful were sold in Canada, so I don't imagine Nishiki made a special batch with Canadian serial numbers.
