I'm sure the experts will chime in, but to my knowledge, the 1990 Paramounts were built either in Waterford or Japan. The Japanese ones have a unicrown fork. The purists among us say Waterford is preferred, but I think that's just jingoism speaking. I have a '92 Panasonic built Paramount, and have never ridden anything even close to that heavenly ride.
That said, I'm aware that you are a collector of fine bicycles, and so might be included in the purist camp.
