^ Nice. The wheels are probably good to go, then. They Might even be easily upgraded by just putting on a 8/9sp cassette and shifters. As for them being original, personally I have no clue. The early 90’s were a time when a lot of bikes might still have a freewheel if it wasn’t a higher end bike, but plenty mid-range did come with modern freehubs too. Just depends on the bike.
