I think surpmil has hit the nail right on the head. I felt that there was the air of a dutch auction going on between this site and that auction site. What you have is highly desirable and will sell easily.
I would imagine that a hundred or so No32/L1A1 sights have been sold on ebay without let or hinderance and just sailed through the process. That this one failed is telling. Additionally, don't egg the story either. It's a relatively modern(?) L42 rifle scope and chest that hasn't been in the US that long relatively speaking so those that do know these things might be suspect. Just tell it as it is............
Take a tip Dutch and accept the withdrawal with good grace and let an ebayer who has experience with the auction site write the carefully worded description for both articles for you.
Don't be parochial either. If someone wants the chest in another country, then tell him to arrange shipping via UPS/TNT etc etc. It works. I've just done it, not 3 weeks ago for an L96 chest that went to Oz
