Pic #4 is interesting as it is stated to be unknown date. Well it is the same shot as discussed as http://ww2chat.com/forums/general-topics/4785-market-garden-drop.html Interestingly, one of the pics has been reveresed - but which one?
Amazing in deed ... Really like Photo #13, the long exposure makes the "tracer" look fantastic ... Wouldn't care to be on the other end of that lot.
