One piece fairing by Paul McGuinness - written 19/09/2011 15:13:19

I was wondering about the one piece fairing I have at home. Was this a part from the factory race team and is it a standard part or not?? Also I have the fibre glass seat section with the word Avon written through it and the bird symbol. Does anyone know about the history of these parts?? 

   I am currently just embarking upon the rebuild of another Cotton (Twin Carb) and would like to keep it as authentic as possible. Where can I find information about the parts and technical drawings Etc... to help locate the parts needed and construction of each section.
