Just to say thanks for taking the trouble to put this thread together, I have been thinking of doing some coach kit building myself for some time but it had seemed rather a leap in the dark; as you said initially, there seemed to be a paucity of practical information available on the web. If it's any help for you, Mike Howarth has some internal plastic seating and corridor divides on Ebay at the moment; also BR Lines has a range of internal seating (mostly open I think but they could still be adapted). Anyway, thanks again.
