Hi Laurent
Whilst its true to say there are not many TR specalists in Sctoland something the might be of help to you is the European Breakdown Directory. It list parts and srevices suppliers for TRs thoughout Europe. It has some 43 entries for the UK so at least you would have a list of specalists that you could contact if you needed to while on your trip. It is available from the TR Register Office at about €5.00 plus p&p.
Hope you have a good trip.
