Rear hub definitely a Pace threaded rear hub, they used to have the earlier "serif" style decals in Black but they always peeled off very easily
RC100 BB shells are 95mm in width, to skim this down to 68mm and then cut BB threads will have taken the crank arms very close to the chain stays unless the BB spindle is very long...
Looks like a heavy re-paint, you should be able to see the Frame number on the BB shell, if it's a re-paint this will probably be full of paint ~ would be interesting to know the frame number?
Fork elastomers will have broken down I would guess, case of undoing the long Allen bolts at the bottom of each leg and sliding them off, would guess you will find a load of perished bits
Tim (justbackdated) or Pace still sell spares
