Meanwhile, Chessbase's "Christmas Puzzles" brings news of a new example
of a game reconstructible from it's final move, found by Stuart Rachels:
see <http://en.chessbase.com/post/chessbase-chrismas-puzzles-2015-7>
(I see that it's already on F.Labelle's page
<http://wismuth.com/chess/problems-moves.html>,
together with confirmation that it's new and has a unique solution).
