Carver,
Welcome to Dalton Forums.
Your knife is a Millennium for sure and was produced in 1997. It is not 1 of 18 either, that was just a dealers sales pitch.
The first two letters in your serial numbers are FO meaning Front Opener, the next four are the numbers 0182 meaning the 182nd knife produced in a series of how many were made. If you look closely at the first three you will see the difference between the letter O and the number 0. See O, 0.
