Hello Roy, Logically it would make economic sense to standardise as many items as possible. Maybe it is a case of being seem to support local manufacturers. There are quite a few differences between UK made tractors and those which came from the plant in Beauvais France. The instrumentation is mainly by Jaeger, not Lucas. Starter motors are Paris-Rhone or Ducellier, not Lucas. The front 10 inch or so, section of the bonnet is often removable. Items like the foot throttle are of a pressed steel construction and not the cast ones that we have in the UK. Naturally all of the instructions would be in French, German or whatever country it was destined for. The flat-top fenders (different design to UK ones) would have a seat and back-rest incorporated normally on the left hand side to carry a passenger. This of course is illegal in the UK.
And most importantly of course they would be right hand drive whereas ours in the UK would be left hand drive ;0))))))))))))))
