Geoff those are current or recent lenses. Chris' lens is 30 years old.
Manufacturers are/(were, rules may have changed) only obliged to keep spares for products up to 10 years old. This is why there was little fuss when Nikon moved to AiS lenses there were no aperture rings for the pre-Ai lenses but some of us accepted it and modified the aperture ring by filing it!
Hope I am wrong and that Nikon UK can supply Chris' rubber ring for his lens.
Both lenses are relatively recent though the 24-70 f2.8 has been replaced by the 24-70 f2.8 VR.
I would still try Nikon first if it is only the rubber covering, if the focusing action is stiff that is another matter.
