(N7...). I have an Ironman Expert with an N7M... serial
number and it is definately a 1988 MODEL. It's red and white
"fade" color scheme (white fork, head tube, faded white-to-
red down and top tubes and faded red-to-white seat and chain
stays) tell me that.

The graphics, components and serial number all confirm a 1987 model, produced in late June or very early July of 1987.
