Picked this up today for $50 from Craigslist for my wife or daughter. It was sitting in some guy's basement for 15 years, and was ridden very little before that. The suicide lever is dated 10/87 and the front brake is dated 3/87, so I'm guessing it is a 1988 model. I spent a couple hours cleaning and it looks great.

There were two numbers on the bottom bracker: OC 054 and F7124980; not sure which is the serial number. One little scratch on the frame but otherwise in terrific condition and was clearly not ridden much before it went into mothballs.
