"Orbiter OK-2.01...was dismantled and sat gathering dust at the Tushina factory near Moscow for years until 2011 when it was reportedly moved to an aviation museum in Germany for restoration"
I just walked through this Buran model a few months ago at the Technikmuseum in Speyer, Germany. It's really there.
The local story (in short) actually is: The director of the museum saw a documentary about a plane graveyard in Bahrain that was aired next to the Formula 1 race there. He saw the Buran in the background, contacted the relevant people and got one short after :).
There was one of the atmospheric test frames just sitting in a vacant block on the outskirts of Sydney about a decade ago. I climbed all over it with a friend one night.
