This thing called NOS happens... a NOS cdale track is just a coincidence. I'm sure the LBS was unable to move it back in 94' (I'm sure sw33t fixie and swag didn't happen yet) and they forgot about it.
Yes, there's even NOS complete bikes since the 80's/ 90's, some still in box.
If I were to buy it, I'd keep it that way.
