Neil,
Sorry for my late reaction, been very busy lately. Anyway, I really like your plan for the
F8 you recently bought!
As for original blueprints, I would follow up the leads posted in the
earlier thread on this type of vehicle. Then, contact:
- the RAF Museum, as I think they ordered the conversion: http://www.rafmuseum.org.uk/
- National Motor Museum: http://www.beaulieu.co.uk/
- local municipal museum(s) of the towns where Duple and Stewart & Ardern were located; they may have taken over files when the companies closed or moved.
And buy a book on coach building, to learn about the tips & tricks of building a coach-built body.
Good luck and keep us posted!
Hanno
