A 1985 Raleigh Royale has been brought into use as a replacement, but I expect this will be for local use and there will be a procurement exercise for a new touring bicycle.
So my question can now be generalised to:
In the current new 'pseudo-classic' touring bike market what component level incompatibilities should you be aware of?
(For example, the Raleigh appears to have the Raleigh bottom bracket, which I would not know where to seek a replacement for, with the increasing development of new proprietary specs I suspect there could be equivalent modern incompatibilities.)
This relates to Western Europe so the 700C/26 inch debate is probably not part of the issue.
1985 bike won't have Raleigh's special [rude word removed]
size bottom bracket thread....Sheldon Brown will probably list when they stopped that particular unforced error.
Front canti studs will probably be the old spacing of about 65mm rather than the current 80mm, this means you need to source any replacement front brake carefully.
Rear dropouts will be spaced for a narrower wheel than the current 135mm touring bike (MTB) stuff. A steel frame is easily re-set.
inch threaded headsets are easily available, stems also
