Thanks, T-Mar. I actually didn't have any data to indicate that my 1500 fork is cr-mo other than it is identical to the 2000's in every way (other than the lack of low-rider bosses), from the crown to the forged ends. I'm actually bothered now with the idea that my 1500 might have hi-ten stays and fork. Digging around a little and delving into the Tange catalog from the early 80s, based on the illustrations of the different options, it appears that the fork is chromoly. They show several fork crown and fork end options for their cr-mo forks and for their hi-ten forks, and mine only matches to the their cr-mo options. Given the date-stamp disparity, it is consistent with the fork having been replaced. However, if that were the case, the replacement had the identical color to the original. I guess I'll never really know for sure!
