Serial number is 249. Despite a few scratches it`s still got the protective film over most of the decals. I bought it off a lady who was Duncan Macdonalds girlfriend back in the 90`s. I sure she said she had another RC100 which had a really low serial number. It had grease ports everywhere, on the thumbies, middle of the shimano hub bodies, two on the rear mech, as well as the normal ones on the headset & bottom bracket.
