Thanks
Well thank you chaps for the replies. I wasn't too sure of what to expect with my request here to be honest. You haven't disappointed!
Sidewinder components are readily available to joe public, you just need to look. I have a complete set of engineering drawings, so if I cannot find an original body, I can make one. So any help finding any section of the body would be great.
I look forward to the attic clear out Courtney Mil, if you need a hand, let me know....
