I got to see this awesome Buran in Gorky Park in Moscow. As far as I know (according to Astroanutix.com) this was a full engineering development version, basically a complete Buran but with no reentry heat protection. It was converted into a ride/experience for a few years but didn't look like that was still happening when I saw it.
Oh and there was a little obs in Gorky Park too
