No, it's a 1990 model, as I previously stated. Based on the serial number, this frame was the 1?98th manufactured on day 140 of 1990. That would make it May 19, 1990. The format used by Raleigh's Kent facility used the 1st and 5th characters as the year indicator. Characters 2 through 4 indicate the day, while the remaining characters are the sequential frame number. Sometimes, there is also an A or B suffix to denote day and evening shifts respectively.
