That's definitely a 1992, as the 1991 was spec'd differently and not available in that color, which Nishiki called Electric Yellow. Frame was spec'd as "CrMo main tubes" so it's they're almost certainly plain gauge and mated to hi-tensile stays. Did you post the s/n to the Nishiki Serial Nmber Database thread? If so, I've already got it, If not, please post. TIA.
