Muzeul Tehnic 'Profesor Inginer Dimitrie Leonida'

This museum in Bucharest used to have at least four airframes displayed.

Bu133 Jungmeister YR-AHM - last reported & photographed 1975; reported destroyed in a roof collapse in the 1980's
IAR817 YR-ASB - no dates, but not there in Mar11 when I visited
IAR813 YR-IBB - outside under covers in poor condition (photographed) in 2000, but not seen in Mar11
primary glider '220' - last reported 1975 (can be seen in photos of the Jungmeister); maybe also destroyed in the roof collapse.

Is this all true? And are there no airframes there now? I was told not when I visited in 2011, but ....

Thanks,

Steve
