What were the pictures of? All externals from loads of silly angles, or did you take it apart to show the condition of the gearbox or something?
When I was showing my SCAR to someone for a trade a while ago (it fell though) I took about 17 photos that showed everything from the externals to the internals, and all the little niggly bits that I thought it was worth pointing out because you need to keep an eye on them.
