Nice example of the differences we can note. Tange labels are consistent with US models from '85-'87.
Not sure about the wheels, as the rear is not QR, and is a wider, "shouldered" model more consistent with the Lemans and Lemans RS. I can't tell about the front. Font is consistent with Centurion from '86 to '89, but I'm not sure if the Lemans models had lettering on the seat stays in '88-the Ironman models didn't (squiggles instead). The graphics between and around the fonts are interesting, not the myriad of geo-shapes of the '88s, but more than some other years in that range.
