I think headset, crankset, brakes, fd, stem, and seatpost binder bolt are original. Yeah, and maybe I misspoke about QC. I think the shifting is cleaner with 6400 series. QC is about the same.
It came to me mainly as "original" (including the OEM chain) but it's not a museum piece, hence my modifications. If you're only going by the catalogs, I think that is a mistake as there was variation in what the companies put on the bikes when shipped as well as modifications at the shop. There are always two steps from the catalog: factory assembly and bike shop assembly.
